[PATCH 5/6] drm/cirrus: Check for pitch limits rather than bpp limits

The real HW limit that prevents from using 32bpp is a pitch limit of 4095 bytes. 32bpp is otherwise supported and works. This fixes the checks in the code to check the right thing (so that a userspace request to set a mode with a supported bpp but a too large pitch will fail appropriately).
