drm/i915: Configure AUX_CH_CTL when enabling the AUX power domain
Most of the AUX_CH_CTL flags are concerned with DP AUX transfer
parameters. As opposed to this the flag specifying the thunderbolt vs.
non-thunderbolt mode of the port is not related to AUX transfers at all
(rather it's repurposed to enable either TBT or non-TBT PHY HW blocks).
The programming has to be done before enabling the corresponding AUX
power well, so make it part of the power well code.
v3:
- Use existing enable/disable helpers instead of opencoding. (Jose)
- Fix type of is_tc_tbt to remain a bitfield. (Lucas)
- Add comment describing the is_tc_tbt power well flag. (Lucas)
