[PATCH] drm/i915/dp: remove redundant link state check

[tarund18303@gmail.com]

From: tarun-tarun143 <tarund18303@gmail.com>

The DP link state is now checked and recovered after link training,
including after modesets. The same recovery path is also used from
the hotplug and HPD IRQ paths.

The link state check from intel_dp_detect() is therefore redundant.
Remove it and rely on the existing link recovery paths.
