Actually, I do not think this is a correct approach. While Moorestown does
not have i8042 theoretically it is possible to add AT-style keyboard by
other means (however unlikely it is) so we should not be disabling it.

We should, however, disallow i8042 from being selected. Could you please
tell me if the patch below works for you?

Thanks!

Input: fixup X86_MRST selects

From: Randy Dunlap <randy.dunlap@oracle.com>

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.
