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

commit cb31c58e8c294ff31ea842ee1fa2c06c9a9f1cc3 upstream.

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.
