Well, I may be mistaken here but it appears to me that amdpm and nfsmb
are very very close in what they support.  Rather than have a couple
of drivers that deal with chips that are basically the same.

In nfsmb_softc - have a set of "operation" function pointers that
define the operations for send/write/receive/read and when the attach
is done populate those pointers with the correct functions (either
amdpm_smbus_* or nfsmb_* functions).  Then in the XXX_exec() usec the
ops defines in the sc instead of calling the functions direct, sort of
like what is done in src/sys/dev/ic/nslm7x.c but for a smbus
controller.  Does that make sense?
