This read wake with retries were initially added by 2 commits:
commit 61da5fab ("drm/i915/dp: retry link status read 3 times on failure")
commit 899526d9 ("drm/i915/dp: try to read receiver capabilities 3 times when
detecting")
Both mentioning section 9.1 of the 1.1a DisplayPort spec, that
Mainly aux communications on sink_crc
were failing a lot randomly on recent platforms.
The first solution was to try to use intel_dp_dpcd_read_wake, but then
it was suggested to move retries to drm level.
Since drm level was already taking care of retries and didn't want
to through random retries
