drm/msm/a3xx: remove TPL1 regs from snapshot
[ Upstream commit f47bee2ba447bebc304111c16ef1e1a73a9744dd ]
These regs are write-only, and the hw throws a hissy-fit (ie. reboots)
when we try to read them for GPU state snapshot, in response to a GPU
hang. It is rather impolite when GPU recovery triggers an insta-
reboot, so lets remove the TPL1 registers from the snapshot.
Fixes: 7198e6b03155 drm/msm: add a3xx gpu support
