drm/nouveau/devinit/tu102-: wait for GFW_BOOT_PROGRESS == COMPLETED

Browse source

[ Upstream commit d22915d22d ]

Starting from Turing, the driver is no longer responsible for initiating
DEVINIT when required as the GPU started loading a FW image from ROM and
executing DEVINIT itself after power-on.

However - we apparently still need to wait for it to complete.

This should correct some issues with runpm on some systems, where we get
control of the HW before it's been fully reinitialised after resume from
suspend.
