Hi All,

Some x86 platforms like intel MID platforms don't have i8042 controllers,
and i8042 driver's probe to some non-exist legacy IO ports may hang
the MID processor. 

Current solution for this is add dependency of SERIO_I8042 over
!X86_MRST, then if we build a x86 kernel image with X86_MRST=y,
it won't have i8042 driver support over common x86 platforms.

So we add a i8042 pre-detect hook into x86_platforms ops, so that
i8042 driver can use it to run-time judge whether to go on with
probe process.

Please review these patches.

Thanks,
Feng
