[PATCH 1/2] Revert "nouveau/gsp: fix suspend/resume regression on r570 firmware"

[Lyude Paul <lyude@redhat.com>]

This reverts commit 8302d0afeaec0bc57d951dd085e0cffe997d4d18.

It turns out this looked like the right fix on some systems, but it's not -
as this causes runtime PM to actually fail on many a laptop.
