[PATCH 14/23] drm/format-helper: Use struct drm_pixmap for drm_fb_xrgb8888_to_xbgr8888()

[Thomas Zimmermann]

Store the source-buffer parameters of drm_fb_xrgb8888_to_xbgr8888()
in struct drm_pixmap. Update the function's interface and all of its
callers.

Callers of drm_fb_xrgb8888_to_xbgr8888() 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.
