[PATCH v4 07/21] rockchip/vpu: Add missing dont_use_autosuspend() calls

[Boris Brezillon <boris.brezillon-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>]

From: Jonas Karlman <jonas-uIzNG4q0ceqzQB+pC5nmwQ@public.gmane.org>

Those calls are needed to restore a clean PM state when the probe fails
or when the driver is unloaded such that future ->probe() calls can
initialize runtime PM again.
