drm/i915/dp: Drop redundant AUX power get/put in intel_dp_force()

Browse Source 
intel_dp_force() takes the AUX power reference as required by the DP AUX
transactions in intel_dp_set_edid(). However the low level AUX handler
takes this reference already so the get/put in intel_dp_force() can be
dropped. This also fixes a problem where the TC port mode changed while
the AUX power well was enabled.
