[PATCH 0/4] drm/i915/dp: aux and dpcd fixes

I haven't received confirmation from various bug reporters whether these
actually fix any issues, but here goes anyway.

We may want to revisit patch 2/4 in a future patch, adding some
heuristic to increase delay with each retry, and maybe taking into
account i2c bit rate capabilities if reported in dpcd.

BR,
Jani.

drm/i915/dp: retry i2c-over-aux seven times on AUX DEFER
drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER
drm/i915/dp: downstream port capabilities are not present in DPCD 1.0
drm/i915/dp: read DPCD PSR capability only on eDP
