drm/i915/psr: Check drm_dp_dpcd_read return value on PSR dpcd init
[ Upstream commit 9cc10041e9fe7f32c4817e3cdd806ff1986d266c ]
Currently we are ignoriong drm_dp_dpcd_read return values when reading PSR
and Panel Replay capability DPCD register. Rework intel_psr_dpcd a bit to
take care of checking the return value.
v2: use drm_dp_dpcd_read_data
