[PATCH] drm/fbdev-dma: Fix framebuffer mode for big endian devices

[Thomas Huth]

The drm_mode_legacy_fb_format() function only generates formats suitable
for little endian devices. switch to drm_driver_legacy_fb_format() here
instead to take the device endianness into consideration, too.

 Note: Patch has only been compile-tested since I lack an environment
       for testing it. But it's the same fix as I required for the
       drm_mode_legacy_fb_format() in drm_fbdev_generic.c / drm_fbdev_ttm.c
       so I think this should be fine.
