So far the driver was configuring the supertiles to be less than 256. But actually, there can be up to 256, not strictly less than 256. There is one restriction though: the frame width or height in supertiles must be less than 256. It also moves this limit to the limits file, which is shared by v3d and v3dv. Signed-off-by: Juan A.
