This commit switches the default case to handle the newest chipsets. This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch them for C51 but traces of the NVIDIA binary driver show it being done there. I couldn't find NV41/NV45 traces to confirm the behaviour there, but an educated guess was taken at each of them.
