drm/i915: Fix psr sink status report.
First of all don't try to read dpcd if PSR is not even supported.
But also, if read failed return -EIO instead of reporting via a
backchannel.
v2: fix dev_priv: At this level m->private is the connector. (CI/DK)
don't convert dpcd read errors to EIO. (DK)
Fixes: 5b7b30864d1d ("drm/i915/psr: Split sink status into a separate debugfs node")
