x86: consolidate the cpu/ related code usage

The x86_64 arch/x86/kernel/Makefile uses references into 
arch/x86/kernel/cpu/... to use code from there.

Unifiy it with the nicely structured i386 way and reuse the existing
subdirectory make rules.

Also move the machine check related source into ...kernel/cpu/mcheck,
where the other machine check related code is.

No code change.
