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

[ Upstream commit 9d6ccfc04fdc5f490f50902d5dae9f53163aa358 ]

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.
