[TGL] Warning "Combo PHY A HW state changed unexpectedly"

This warning was introduced because of the new combo phy sequence implemented in "drm/i915/display: Implement new combo phy initialization step". This is probably due a old IFWI firmware being used in CI but issue will be kept open until fixed by IFWI upgrade or code changes.

Looking at the HSD(22010518810) of the new step, it requires changes in IFWI. So I check the checked the IFWI versions of TGL shards:

shard-tglb1:

DMI: Intel Corporation Tiger Lake Client Platform/TigerLake U DDR4 SODIMM RVP, BIOS TGLSFWI1.R00.3197.A00.2005110542 05/11/2020

shard-tglb3:

DMI: Intel Corporation Tiger Lake Client Platform/TigerLake U DDR4 SODIMM RVP, BIOS TGLSFWI1.R00.3197.A00.2005110542 05/11/2020

shard-tglb2:

DMI: Intel Corporation Tiger Lake Client Platform/TigerLake U DDR4 SODIMM RVP, BIOS TGLSFWI1.R00.3197.A00.2005110542 05/11/2020

All of those are previous to the release of the IFWI with the required changes, can we have a IFWI upgrade in CI? The upgraded IFWI will fix this issue, this issue do not happen in my TGL with a updated IFWI.

Assigning to Radoslaw.

It also affects dg1. By this point isn't time to accept that the old fw is bust, and ignore the discrepancy if it does not lead to further issues. For which a dbg message suffices.

added platform: DG1 label

Saw the same problem with a DG1 with older firmware. I agree to change to debug just for this 2 platforms, otherwise we could be hiding unknown issues under it.

@jani.saarinen @random_james CCing more people to try to get CI updated to the latest firmware.

removed platform: DG1 label
