To prepare the introduction of tiled mode support, pass the framebuffer
format modifier to the helpers dealing with format support.
Since only linear mode is supported for now, add corresponding checks in
each helper.

This introduces support for the BGRX8888 input format for the frontend,
with its associated pixel sequence value definition. Other fields are
already configured correctly as they no longer depend on the format's
fourcc directly.

This introduces proper definitions for the input and output format
configuration registers instead of a macro and raw values in the code,
with the intent to increase code readability and reduce indirections.

In order to check whether the frontend supports a specific format, an
explicit list and a related helper are introduced.
Just like in the backend, the prototype of the helper is added to the
frontend header so that it can be used later on. The helper is also
exported because it will be used outside of the frontend module.
