mt76x0e driver only supports MAC addresses from
calibration data eeprom. Many routers however do not
have a valid stock address set in this field.
This patch makes it possible to take a MAC address
from OF (e.g. from mtd).

A rcu read locked section is not allowed to sleep, and the rcu lock here
isn't actually necessary, because we're holding dev->mutex.

a station or stopping the aggregation session

With the devm API, the unregister happens after the device cleanup is done,
after which the struct mt76_dev which contains the led_cdev has already been
freed. This leads to a use-after-free bug that can crash the system.
