This patch series enable PC8+ residency test, earlier these tests
were only enabled for Haswell and Broadwell.

I have addressed the below review comment from old series (https://patchwork.freedesktop.org/series/57035/)

1. Made this test future proof to enable for all Gen9+ platform.
2. Added a pc8_needs_screen_off flag to distinguish between HSW/BDW and Gen9+
   Platform.
3. Since Gen9 onwards PC8+ residency doesn't require display to be turned off,
   this patch series tests PC8 residency with all screens on.

Tested on Gen9 KBL Platform, unable to test on ICL, because ICL systems at local
BA setup are not entering to PC2 itself.

Planning a separate series for a subtest to validate pc8 with multiple pipes
usages and all planes enabled with max resolution, to create maximum memory
bandwidth scenario.
