This series contains 3 small pmgr related fixes for Apple silicon devices with M1 and M2.
1. Prevent the display controller and DPTX phy from powered down after initial boot on the M2 Mac mini. This is the only fix worthwhile for stable kernels. Given how long it has been broken and that it's not a regression I think it can wait to the next merge window and get backported from there into stable kernels.
2. Mark ps_atc?_usb_aon as always-on. This is required to keep the soon to be suported USB type-c working across suspend an resume. The later submitted devicetrees for M1 Pro/Max/Ultra, M2 and M2 Pro/Max/Ultra already have this property since the initial change. Only the separate for M1 was forgotten.
3. Model the hidden dependency between GPU and pmp as power-domain dependency. This is required to avoid crashing the GPU firmware immediately after booting.
