media: mali-c55: Power-off the peripheral in remove()

Browse source

The Mali C55 driver doesn't depend on PM. For this reason, if pm_runtime
is not compiled in it is required to manually power-off the peripheral
during the driver's remove() handler.

Also pm_runtime_enable() is called during probe but mali_c55_remove()
never calls pm_runtime_disable(), leaving the device's runtime PM state
enabled after the driver is unbound.

Manually power-off the peripheral in remove() if the peripheral has not
been suspended using runtime_pm and disable runtime pm.
