Modify the overlay driver data for MT8195 to enable bit depth control and
enable support for AR30 and BA30 framebuffer formats. This patch in
combination with the previous two patches in the series will allow MT8195
devices to scanout AR30 and BA30 framebuffers.
Tested using "modetest -P" on an MT8195 device. The test pattern displays
correctly for both AR30 and BA30 formats.
