[PATCH 3/3] nouveau/gsp: fix suspend/resume regression on r570 firmware

[Dave Airlie <airlied@gmail.com>]

From: Dave Airlie <airlied@redhat.com>

The r570 firmware with certain GPUs (at least RTX6000) needs this
flag to reflect the suspend vs runtime PM state of the driver.

This uses that info to set the correct flags to the firmware.

This fixes a regression on RTX6000 and other GPUs since r570 firmware
was enabled.

Signed-off-by: Dave Airlie <airlied@redhat.com>
Fixes: 53dac0623853 ("drm/nouveau/gsp: add support for 570.144")
Cc: <stable@vger.kernel.org>
