Thomas Zimmermann	b3728905dc	drm/sysfb: Generalize pixel-format matching ... Provide drm_sysfb_get_format(), a helper that finds a specific DRM format from a list of pixel formats. The new function builds upon drm_sysfb_get_format_si(), which finds the DRM format from a given instance of struct screen_info. Now get the screen_info's pixel format in the caller. Allows for matching pixel formats in drivers without screen_info. Convert the callers in efidrm and vesadrm to the new interface.
