Add two remaining bits necessary to enable Adreno A225 support.
Note, this wasn't tested on the actual hardware and is purely based on
the old KGSL driver from msm-3.0. For example, running on MSM8960 might
require adjusting PM_OVERRIDE[12] registers.

Not sure that's enough, a2xx_drawctxt_draw_workaround looks scary

Yep. msm-3.0 does some other things for a200 / a220, which we don't
perform. I don't know which parts actually apply to our stack and which
don't.

Right, this patchset at least fixes up the obvious errors and those
interested can poke at it more
