powerpc/pci: Fix return type of BUID_{HI,LO} macros
BUID_HI and BUID_LO are used to pass data to call_rtas, which expects ints or u32s. But the macro doesn't cast the return, so the result is still u64. Use the upper_32_bits and lower_32_bits macros that have been added to kernel.h. Found by getting printf format errors trying to debug print the args, no actual code change for 64 bit kernels where the macros are actually used.
