This cleans up a few MSR-using drivers in the following manner:
- Ensures MSRs are all defined in asm/geode.h, rather than in misc
places
- Makes the naming consistent; cs553[56] ones begin with MSR_,
GX-specific ones start with MSR_GX_, and LX-specific ones start
with MSR_LX_. Also, make the names match the data sheet.
- Use MSR names rather than numbers in source code
- Document the fact that the LX's MSR_PADSEL has the wrong value
in the data sheet. That's, uh, good to note.
