drm/sun4i: layer: Add tiled modifier support and helper
This introduces a list of supported modifiers for the driver, that
includes the Allwinner tiled modifier, as well as a format_mod_supported
callback.
The callback uses both the backend and frontend helpers to indicate
per-format modifier support (including for the linear modifier).
