Turn off display power at the end of controller resume flow. This is now possible with the changes done in commit 87fc20e4a0cb ("ASoC: SOF: Intel: hda: use hdac_ext fine-grained link management"). As codec driver is able to request the HDA link to be brought back up, the controller no longer needs to blindly keep display power enabled.
