mb/google/brya/var/agah: Optimize dGPU GCOFF entry
After staring at lots of scope shots, the EE has determined that a few
modifications to the GCOFF sequence can be made:
- Remove delay between PERST# assertion and GPU_ALLRAILS_PG deassertion
- Remove delay after ramping down FBVDD
This patch implements these minor changes.
