Instead of calling intel_dp_set_signal_levels(), which writes the
desired signal levels mask to a variable, just call the new function
intel_dp_update_signal_levels(). The effect should be the same, except
for an extra register write, but this creates a better split between the
generic link training logic and the i915 specific part.
