PS2Mult is a simple serial protocol used for multiplexing several PS/2
streams into one serial data stream. It's used e.g. on TQM85xx series
of boards.

This reverts commit 0b28bac5aef7bd1ab213723df031e61db9ff151a.

After adding x86_platform's detection for i8042 controller, we
don't need the force dependency on !X86_MRST any more

Some of the recent X86_MRST additions make some "select"s
conditional on X86_MRST but missed some related kconfig symbols,
causing:

drivers/built-in.o: In function `ps2_end_command':
(.text+0x257ab2): undefined reference to `i8042_check_port_owner'
drivers/built-in.o: In function `ps2_end_command':
(.text+0x257ae1): undefined reference to `i8042_unlock_chip'
drivers/built-in.o: In function `ps2_begin_command':
(.text+0x257b40): undefined reference to `i8042_check_port_owner'
drivers/built-in.o: In function `ps2_begin_command':
(.text+0x257b6f): undefined reference to `i8042_lock_chip'

when SERIO_I8042=m, SERIO_LIBPS2=y, KEYBOARD_ATKBD=y.

We need to make i8042 dependant upon !X86_MRST and allow deselecting
atkbd on Moorestown even when !CONFIG_EMBEDDED.

The sh64 cayman platform is the only sh board that ships with an i8042,
so we just hide it for all of the others.

The patch introduces a serio driver that supports a keyboard serial port found
on the Amstrad Delta videophone board.

After initializing the hardware, the driver reads its input data from a buffer
filled in by the board FIQ (Fast Interrupt Request) handler.

Standard AT keyboard driver (atkbd) will be used on top of the serio layer for
handling the E3 keyboard (called mailboard) connected to the port. Since the
device generated scancodes differ from what the atkbd expects, a custom key
code to scan code table must be loaded from userspace for the keyboard to be
useable.

libps2 can not be built in if i8042 is a module, all other combinations
are allowed.

The CLPS7500 platform has not built since 2.6.22-git7 and there
seems to be no interest in fixing it.  So, remove the platform
support.

Added a new driver for Xilinx XPS PS2 IP. This driver is
a flat driver to better match the Linux driver pattern.
