Combo PHY ports require the AUX_IO power only for eDP/PSR, so don't
enable it otherwise on these ports. So far the external DP and eDP case
was handled the same way due to unclarity when AUX_IO for the main link
is needed. However Bspec is clear in which cases it's required:
- eDP/PSR on all ports and platforms (presumably due to HW/FW initiated
PSR transactions that won't enable AUX_IO)
Bspec: 4301, 49296
- TypeC PHY ports on platforms before MTL in all TypeC modes (TBT,
DP-alt, legacy) and for both HDMI and DP. The next patch will take
into account the pre-MTL platform dependency.
Bspec: 22243, 53339, 21750, 49190, 49191, 55424, 65448, 65750, 49294,
55480, 65380
v2:
- Rebased on checking intel_encoder_can_psr() instead of crtc->has_psr.
