[ARM] 3860/1: Versatile PCI config byte accesses
The ARM Versatile board PCI config space read routines are broken for byte
accesses. The access uses a byte read, so masking the bottom two bits of the
address is wrong.
I guess this is a cut/paste error from the the halfword code which uses
aligned word access+shift+mask.
