x86: Work around mmio config space quirk on AMD Fam10h
Some broken devices have been discovered to require %al/%ax/%eax registers
for MMIO config space accesses. Modify mmconfig.c to use these registers
explicitly (rather than modify the global readb/writeb/etc inlines).
AK: also changed i386 to always use eax
AK: moved change to extended space probing to different patch
AK: reworked with inlines according to Linus' requirements.
AK: improve comments.
