Subject: x86: add periodic corruption check

Perodically check for corruption in low phusical memory.  Don't bother
checking at fault time, since it won't show anything useful.

Subject: x86: memory corruption check - cleanup

Move the prototypes from the generic kernel.h header to the more
appropriate include/asm-x86/bios_ebda.h header file.

Also, remove the check from the power management code - this is a
pure x86 matter for now.
