9e2c2e2730 drm/etnaviv: add infrastructure to query perf counter 
Make it possible that userspace can query all performance domains and
its signals. This information is needed to sample those signals via
submit ioctl.

At the moment no performance domain is available.

Changes from v1 -> v2:
- use a 16 bit value for signals
- fix padding issues
- add id member to domain and signal struct

Changes v4 -> v5
- provide for each pipe an own set of pm domains
