That ac97reg.h predates the existance of the Au1550 PSC.  I haven't
looked at the differences between the old (Au1{0,1,5}00) AC97 and new
PSC AC97 to be able to tell if they can share code or not yet.

For SMBus there is no previous driver in the Alchemy parts (although
some Alchemy based boards just used GPIO pins for this), so I think it
might be better to call this psc_smbusreg.h or pscsmbusreg.h or similar.
