msm: kgsl: Add A6XX preemption support
This patch adds the basic a6xx preemption code, which
includes:
1. New PM4 packets sequences which inform the CP of the
outgoing and the incoming contexts.
2. The preemption initialization sequence.
3. Definitions of preemption related registers.
4. The fast preemption code.
