drm/panthor: Fix NULL pointer dereference on panthor_fw_unplug
This patch removes the MCU halt and wait for halt procedures during
panthor_fw_unplug() as the MCU can be in a variety of states or the FW
may not even be loaded/initialized at all, the latter of which can lead
to a NULL pointer dereference.
It should be safe on unplug to just disable the MCU without waiting for
it to halt as it may not be able to.
