drm/nouveau/gsp/r570: Add comp mode workaround from issue #3172217
One of the things that OpenRM does right before initiating fbsr is apply a
special workaround (nvidia issue #3172217) which temporarily disables raw
compression mode on the GPU. It is later re-enabled after resuming with
fbsr completes.
Since we don't currently save the compbit backing with fbsr, this shouldn't
currently make any functional difference in the suspend/resume process. But
it will be required for implementing support for saving and restoring
compbit backings from the GPU.
