From: Gustavo Padovan gustavo.padovan@collabora.co.uk
XR24 planes were not shown properly, so now set the right registers to correctly enable displaying these planes.
It also moves the alpha register settings to fimd_win_set_pixfmt() to keep all pixel format stuff together.
v2: remove leftover var alpha
