[PATCH] xv: fix non-kms/non-dri Xv column ordering on big endian systems

[Heikki Lindholm]

Column order is wrong on big endian systems, primarly because of a
bits / bytes mix up with the bpp variable. Fix tested with r100 and
r300, screen depth 16 and 32 with YV12 and YUY2 (overlay, textured video),
RGBA and RGBT (overlay).

Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=29041
