drm/i915 Call get_adjust_train() from clock recovery and channel eq
Move the call to intel_dp_get_adjust_train() out of
intel_dp_update_link_train() and call it instead from the clock recovery
and channel equalization features. A follow up patch will remove the DP
register write from that function, so that it handles only the DPCD
write.
