drm/mgag200: Enable DRM_FORMAT_XRGB1555 on the primary plane

Browse Source 
The driver already sets the format for the depth value in the XMULCTRL
register. Add the format to the other switch statements, set the helpers
for gamma correction and export the XRGB1555 in the primary plane's
format array.
