[Intel-gfx] [PATCH 06/11] drm/i915/display/dp: Do not enable PSR if VRR is enabled

[Manasi Navare]

Even though our HW supports PSR + VRR, the available panels
do not work reliably with PSR and VRR together. So if user
requested VRR and is supported by HW enable that and do not
enable PSR in that case.
