Imre Deak e393d0d6c1 drm/i915/lspcon: Switch back to PCON mode after output replug
At least a ParadTech PS175 LSPCON chip/firmware uses long instead of
short pulses to signal output unplug/plug events. This is contrary to
how branch devices normally work which use short HPD signaling. This
chip will also switch to LS mode after an unplug event, which could be
the consequence of the long HPD signaling semantics and an effort to
save power automatically. Because of this we'll fail to do AUX and
detect the output after a replug event.

To fix this make sure we are in PCON mode during connector detection.

v2:
- Switch the mode in the proper spot.
