From: José Roberto de Souza <jose.so...@intel.com>
On ADL-P TC cold is exited and blocked when legacy aux is powered,
that is exacly the same of what ICL need for static TC ports.
TODO: When a TBT hub or monitor is connected it will cause TBT and
legacy aux to be powered at the same time, hopefully this will not
cause any issues but if it do, some rework will be needed.
