Store the source-buffer parameters of drm_fb_xrgb8888_to_argb2101010()
in struct drm_pixmap. Update the function's interface and all of its
callers.
Callers of drm_fb_xrgb8888_to_argb2101010() initialize the pixmap's
instance from a pre-existing instance of struct drm_framebuffer.
There's potential to simplify some of that code in a later patch.
