drm/i915/dp: try to read receiver capabilities 3 times when detecting
If ->detect is called too soon after a hot plug event, the sink may not
be ready yet. So try up to 3 times with 1ms sleeps in between tries to
get the data (spec dictates that receivers must be ready to respond within
1ms and that sources should try 3 times).
See section 9.1 of the 1.1a DisplayPort spec.
