Update XRGB8888-to-RGB888 conversion to support struct iosys_map and convert all users. Although these are single-plane color formats, the new interface supports multi-plane formats for consistency with drm_fb_blit(). v2: * update documentation (Sam) * add TODO on vaddr location (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220808125406.20752-8-tzimmermann@suse.de
