mb/google/brya/var/agah: Add delays to GPU power off sequence

During the GPU power down sequence, each power rail should reach below
at least 10% before the next rail is sequenced down; based on scope
shots for a board, conservative delays between each rail are added;
they will likely be more fine-tuned later on.
