[POWERPC] Demacrofy arch/powerpc/platforms/maple/pci.c
Noticed that the U3_*CFA macros have some typos:
#define U3_HT_CFA0(devfn, off) \
((((unsigned long)devfn) << 8) | offset)
(refers to offset rather than off)
#define U3_AGP_CFA0(devfn, off) \
((1 << (unsigned long)PCI_SLOT(dev_fn)) \
| (((unsigned long)PCI_FUNC(dev_fn)) << 8) \
(refers to dev_fn rather than devfn)
Things happen to work, but there doesn't seem to be any reason these
shouldn't be functions. Overall behavior should be unchanged.
