This patch fixes the naming of the registers:

s/PIPE_DSS_CTL/ICL_PIPE_DSS_CTL

And also fix the hex values to lower case, to match
rest of the definitions.

Manasi noticed this with the patch that was merged.

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)

MST ports are allocated from struct intel_dp_mst_encoder not from
struct intel_digital_port as regular ports, so to get the TC type it
is necessary check the primary digital port of the mst encoder.

It is only used by eDP ports so no need to initialize it for each DP
port.

Otherwise it would be in a inconsistent state as port is disconnected
but with a valid tc type.

Otherwise it would be in a inconsistent state as port is disconnected
but with a valid tc type.

Also setting it to unknown will earlier return
icl_tc_phy_disconnect() for any future calls to
intel_digital_port_connected(), this way we don't need to check if
port is marked as safe everytime.

Besides of give the expected output of i915_display_info it will also
avoid some aux ch transactions that would timeout by obvious reasons.

the framebuffer domensions are not suitable for NV12.
