msm: kgsl: Mark the scratch buffer as privileged
Mark the scratch buffer as privileged so that it can only be accessed by
GPU through the ringbuffer. To accomplish this, we need to:
1. Move the preemption data out of the scratch buffer.
2. Disable the shadow rptr feature.
3. Trigger RPTR update from GPU using a WHERE_AM_I packet.
4. Add support for the new ucode.
