drm/i915/panelreplay: Move out psr_init_dpcd() from init_connector()drm-intel-fixes-2024-03-07
Move psr_init_dpcd() from init-connector to connector-detect function. The dpcd probe for checking panel replay capability for external dp connector is causing delay during boot which can be optimized by moving dpcd probe to connector specific detect(). v1: Initial version. v2: Add details in commit description.
