drm/i915/dp: retry link status read 3 times on failure
Especially after a hotplug or power status change, the sink may not reply immediately to a link status query. So retry 3 times per the spec to really make sure nothing is there. See section 9.1 of the 1.1a DisplayPort spec. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by: Keith Packard <keithp@keithp.com> Signed-off-by: Keith Packard <keithp@keithp.com>
