SC8280XP, being a partial derivative of SM8350, shares almost the exact
same videocc block. Extend the 8350 driver to support the bigger brother.
The only notable changes are higher possible frequencies on some clocks
and some switcheroo within the XO/sleep registers (probably due to some
different board crystal configuration).
