Port mt76x02_check_tx_hang watchdog from vendor driver in order to
reset the card when tx mac/dma engine is stucked. Tx mac/dma stuck
occurs when the device is heavily loaded or in a noisy environment.
In that condition tx queues are not drained since the device does not
generate tx interrupts.
This series is based on "add EDCCA support to mt76x{0,2}e drivers"
