sparc64: update IO access functions in PeeCeeI
The PeeCeeI.c code used in*() + out*() for IO access. But these are in little endian and the native (big) endian result was required which resulted in some bit-shifting. Shift the code over to use the __raw_*() variants all over. This simplifies the code as we can drop the calls to le16_to_cpu() and le32_to_cpu(). And it should be a little faster too. With this change we now uses the same type of IO access functions in all of the file. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
