x86: geode: MSR cleanup
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.
