drm/msm/dp: add module parameter for PSR
On sc7280 where eDP is the primary display, PSR is causing
IGT breakage even for basic test cases like kms_atomic and
kms_atomic_transition. Most often the issue starts with below
stack so providing that as reference

[drm-dp] dp_ctrl_push_idle: PUSH_IDLE pattern timedout
Other basic use-cases still seem to work fine hence add a
a module parameter to allow toggling psr enable/disable till
PSR related issues are hashed out with IGT.
