[PATCH] drm/i915/psr: Disable Panel Replay as well if VRR is enabled

[Jouni Högander]

Having Panel Replay enabled together with VRR is causing following errors:

xe 0000:00:02.0: [drm] *ERROR* Timed out waiting PSR idle state
xe 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080
xe 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun
xe 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00040080
xe 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00040080

Let's disable Panel Replay as well if VRR is enabled.
