drm/panthor: Be robust against resume failures
When the runtime PM resume callback returns an error, it puts the device
in a state where it can't be resumed anymore. Make sure we can recover
from such transient failures by calling pm_runtime_set_suspended()
explicitly after a pm_runtime_resume_and_get() failure.
v3:
- Add R-b/A-b
v2:
- Add a comment explaining potential races in
panthor_device_resume_and_get()
