The display backend does not support BGRX8888. There is also no trace
of this in the original list of supported formats before the commit
b636d3f97d04 ("drm/sun4i: frontend: Add support for the BGRX8888 input
format"). Nor do the backend configuration helpers handle this format.

Remove BGRX8888 from list of supported formats by the backend.

Fixes: 3d4265f89d06 ("drm/sun4i: backend: Add a helper and a list for supported 
formats")
