[PATCH v4 2/5] drm/bridge: it6505: disable runtime PM on remove

it6505_i2c_probe() enables runtime PM but it6505_i2c_remove() never
disables it, leaving the device with an unbalanced disable depth
after unbind. Binding the driver again then triggers the "Unbalanced
pm_runtime_enable!" warning.

Disable runtime PM in remove() after all work items have been
cancelled (the extcon work calls pm_runtime_get_sync() and
pm_runtime_put_sync()) and before powering the chip off manually.
