powerpc/io: Add __raw_writeq_be() __raw_rm_writeq_be()
Add byte-swapping versions of __raw_writeq() and __raw_rm_writeq().
This allows us to avoid sparse warnings caused by passing __be64 to
__raw_writeq(), which takes unsigned long:
arch/powerpc/platforms/powernv/pci-ioda.c:1981:38:
warning: incorrect type in argument 1 (different base types)
expected unsigned long [unsigned] v
got restricted __be64 [usertype] <noident>
It's also generally preferable to use a byte-swapping accessor rather
than doing it by hand in the code, which is more bug prone.
