[PATCH 3/3] drm/pl111: Use max memory bandwidth for resolution

We were previously selecting 1024x768 and 32BPP as the default set-up for the PL111 consumers. This does not work on elder systems: the device tree bindings support a property "max-memory-bandwidth" in bytes/second that states that if you exceed this the memory bus will saturate. The result is
