[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.
