[i-g-t V2] tests/intel/pm: Separate display specific tests from i915_pm_rpm
Bhanuprakash Modem

Fri Sep 15 14:22:27 UTC 2023
Separate display specific tests, from i915_pm_rpm and create
a new binary "kms_pm_rpm" for them.
Note: This patch can be split into multiple, but still it is
a good starting point to review.
V2: - Drop unnecessary header files
V3: - Restore old Copyright
- Fix missing display tests
V4: - Fix/Optimize testplan documentation
- Split module-reload into with & w/o display
V5: - Fix testlist in BAT
- Fix double closure of fd
