drm/i915/icl+/tc: Convert AUX powered WARN to a debug message
The BIOS can leave the AUX power well enabled on an output, even if this
isn't required (on platforms where the AUX power is only needed for an
AUX access). This was observed at least on PTL. To avoid the WARN which
would be triggered by this during the HW readout, convert the WARN to a
debug message.
