drm/i915: Take runtime pm reference on hangcheck_info
We read the coherent current seqno and actual head from ring.
For hardware access we need to take runtime_pm reference.
Get hardware specific values with runtime reference held
and print them first to emphasize hw state vs bookkeepping.
v2: Reorder output according to hw access (Chris)
remove superfluous locking (Daniel)
Testcase: igt/pm_rpm/debugfs-read
