drm/msm: Add preemption records to QTI GPU snapshot
This patch helps dump the full 64k per ring preemption
record to GPU snapshot which is collected during GPU
recovery step. We use the general object snapshot section
type to store these records and we only collect the preemption
records if preemption was going to kick in, which is when
the number of rings is greater than one.
