Both of these symbols should be defined by a platform, or neither
should be defined. Ensure that all platforms conform.

As Al did for Versatile in 2ad4f86b60b649fd7428265c08d73a3bd360c81b,
add a typesafe __io implementation for platforms to use. Convert
platforms to use this new simple typesafe implementation.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h,
thereby placing it along side its relative, ISA_DMA_THRESHOLD.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

desc_handle_irq() was declared as obsolete since long ago.
Replace it with generic_handle_irq()

Update DaVinci EVM board setup to work with key drivers which are
now in mainline kernels:
- I2C adapter (driver: i2c_davinci)
* three gpio expanders (driver: pcf8574) used for
- LEDs
- audio codec control
- misc device control (including USB VBUS, IDE-vs-CF)
* at24 (driver: at24) eeprom
- USB controller (driver: musb_hdrc)
- IDE controller (driver: palm_bk3710)
This board is the first in-tree client for a number of those drivers,
and adding this board support means the EVM board can be used for some
"real work" ... excepting "DaVinci Technology" video and DSP support
(also available in most OMAP3 chips).
Also renames the flash as "evm_norflash", since NAND may be jumpered.
(Patch contains work by myself, Kevin Hilman, Sergei Shtylyov.)

Switch DaVinci SOC gpios over to using the new GPIO library, so it can
access GPIO expanders and other non-SOC GPIOs using the same calls.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

We need to make sure, that the clockevent devices are resumed, before
the tick is resumed. The current resume logic does not guarantee this.
Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock
event devices before resuming the tick / oneshot functionality.
Fixup the existing users.
Thanks to Nigel Cunningham for tracking down a long standing thinko,
which affected the jinxed VAIO.
