ppc: Add support for bigendian color byte order
On LE machine, color order when creating surface will always be A/XRGB.
On BE machines the color order will sometimes be ARGB and sometimes BGRA/X.
This is because we actually create the surface two times on BE machines.
Once with BE order, and then again with LE order. Copying data inbetween
theese two surfaces will byteswap the colors automatically.
This change introduces cases for BGRA/X color byte orders on BE machines.
