Separate out ata_dev_reread_id() from ata_dev_revalidate().
ata_dev_reread_id() reads IDENTIFY page and determines whether the
same device is still there. ata_dev_revalidate() reconfigures after
reread completes. This will be used by ACPI update.

ide_use_dma() duplicates a lot of ide_max_dma_mode() functionality
and as all users of ide_use_dma() were converted to use ide_tune_dma()
now it is possible to add missing checks to ide_tune_dma() and remove
ide_use_dma() completely, so do it.
There should be no functionality changes caused by this patch.

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to program PIO5 by config_art_rwp_pio() could result in incorrect PIO
timings being programmed and possibly the data corruption (for < ATA100
family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random
content of test1 variable was used, for ATA133 - MWDMA0 timings were used)
* BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5,
also cleanup this function a bit while at it
* add comment about PIO0 timings for < ATA100 family chipsets
* remove open-coded best PIO mode selection from config_art_rwp_pio(),
it contained numerous bugs:
- it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
before using them
- it tried to found out maximum PIO mode basing on minimum IORDY cycle time
(moreover wrong cycle times were used for PIO1/5)
- it was overriding PIO blacklist and conservative PIO "downgrade" done
by ide_get_best_pio_mode()
* use sis5513_tune_drive() instead of config_art_rwp_pio()
in sis5513_config_xfer_rate() so the correct PIO mode is also set
on drive even if the device is not IORDY/DMA capable
* config_art_rwp_pio() was always setting the best possible mode and not
the wanted one - fix it and move ide_get_best_pio_mode() call to
config_chipset_for_pio()
* don't use ide_find_best_mode() in config_chipset_for_pio(), it was being
overriden by config_art_rwp_pio() for the host timings anyway + we need to
set the same PIO mode on the device and the host
* pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call
in sis5513_config_xfer_rate() so the best PIO mode is set on the drive
and not PIO4
* rename sis5513_tune_drive() to sis5513_tuneproc()
and config_chipset_for_pio() to sis5513_tune_driver()

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to program PIO5 by svwks_tune_chipset() could result in incorrect PIO
timings being programmed and possibly the data corruption (it seems that
the minimum possible values were used but I lack the datasheets to be sure)
* select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset()
when doing PIO autotuning (pio == 255)
* don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could
return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate()
takes care of PIO tuning if no suitable DMA mode is found)
* remove config_chipset_for_pio() and use svwks_tune_drive() instead,
config_chipset_for_pio() contained numerous bugs when selecting PIO mode
(luckily it was only used for devices limited to PIO by capabilities/BIOS):
- it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
before using them
- it tried to found out maximum PIO mode basing on minimum IORDY cycle time
(moreover wrong cycle times were used for PIO0/1/5)
- it was overriding PIO blacklist and conservative PIO "downgrade" done
by ide_get_best_pio_mode()
- if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected
(XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result
was the same as if using XFER_PIO_5 => wrong PIO timings were set)
- it was overriding drive->current_speed
* bump driver version

This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.
Rewrite mode programming code:
* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
even if both devices on the channel are not DMA capable and after reset
* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
as they need to be setup correctly also for PIO only devices, plus IORDY
wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
ATAPI devices
* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
(driver sets ->autotune to 1 so PIO modes are always programmed => lower
nibble of register A never equals 4 => "chipset_is_set" is always true)
* enable PIO mode programming for all ATAPI devices
(it was limited to ->media == ide_cdrom devices)
* remove extra reads of registers A/B/C, don't read register D et all
* do clearing / programming of registers A/B/C in one go
(gets rid of extra PCI config space read/write cycle)
* set initial values of drive_conf/AP/BP/CP variables to zero
(paranoia for the case when PCI reads fail)
* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
(ide_rate_filter() takes care of it)
* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
* fix bitmasks for clearing bits of register B:
- when programming DMA mode bit 0x10 of register B was cleared which
resulted in overclocked PIO timing setting (iff PIO0 was used)
- when programming PIO mode bits 0x18 weren't cleared so suboptimal
timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
* add FIXME comment about missing locking for 66MHz clock register
Also while at it:
* remove unused defines
* do a few cosmetic / CodingStyle fixes
* bump driver version
v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
registers is used only by the debugging code so cover "drive_conf"
PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO
(Noticed by Sergei Shtylyov)

It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.
Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.
