Stanislaw Gruszka 4522ad764d accel/ivpu: Do not access HW registers after unbind 
We should not access hardware after we unbind from the bus.

Use drm_dev_enter() / drm_dev_exit() to mark code sections where
hardware is accessed (and not already protected by other locks)
and drm_dev_unplug() to mark device is gone.
