drm/i915/psr: Disable Panel Replay if PSR mode is set via module parameter
If user is specifically limiting PSR mode to PSR1 or PSR2: disable Panel
Replay. With default value -1 all modes are allowed including Panel
Replay. Disabling PSR using value 0 disables Panel Replay as well.
Also own compute config helper is added for Panel Replay. This makes sense
because number of Panel Replay specific checks are increasing.
v2: Squash adding Panel Replay compute config helper
