scsi: delete the MCA specific drivers and driver code

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes the MCA specific SCSI drivers, and the
MCA specific portions of code in dual role ISA/MCA drivers.
Also, the MCA specific SCSI documentation is removed.

-/* fd_mcs.c -- Future Domain MCS 600/700 (or IBM OEM) driver
- *
- * FutureDomain MCS-600/700 v0.2 03/11/1998 by ZP Gu (zpg@castle.net)
- *
- * This driver is cloned from fdomain.* to specifically support
- * the Future Domain MCS 600/700 MCA SCSI adapters. Some PS/2s
- * also equipped with IBM Fast SCSI Adapter/A which is an OEM
- * of MCS 700.
- *
- * This driver also supports Reply SB16/SCSI card (the SCSI part).
- *
- * What makes this driver different is that this driver is MCA only
- * and it supports multiple adapters in the same system, IRQ 
- * sharing, some driver statistics, and maps highest SCSI id to sda.
- * All cards are auto-detected.
- *
- * Assumptions: TMC-1800/18C50/18C30, BIOS >= 3.4
- *
- * LILO command-line options:
- *   fd_mcs=<FIFO_COUNT>[,<FIFO_SIZE>]
- *

- NOTES ON USER DEFINABLE OPTIONS:
-
- DEBUG: This turns on the printing of various debug information.
-
- ENABLE_PARITY: This turns on SCSI parity checking.  With the current
- driver, all attached devices must support SCSI parity.  If none of your
- devices support parity, then you can probably get the driver to work by
- turning this option off.  I have no way of testing this, however, and it
- would appear that no one ever uses this option.
-
- FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the
- 18C30 chip have a 2k cache).  When this many 512 byte blocks are filled by
- the SCSI device, an interrupt will be raised.  Therefore, this could be as
- low as 0, or as high as 16.  Note, however, that values which are too high
- or too low seem to prevent any interrupts from occurring, and thereby lock
- up the machine.  I have found that 2 is a good number, but throughput may
- be increased by changing this value to values which are close to 2.
- Please let me know if you try any different values.
- [*****Now a runtime option*****]
-
- RESELECTION: This is no longer an option, since I gave up trying to
- implement it in version 4.x of this driver.  It did not improve
- performance at all and made the driver unstable (because I never found one
- of the two race conditions which were introduced by the multiple
- outstanding command code).  The instability seems a very high price to pay
- just so that you don't have to wait for the tape to rewind.  If you want
- this feature implemented, send me patches.  I'll be happy to send a copy
- of my (broken) driver to anyone who would like to see a copy.
