mt76: dma: move mt76x02_init_{tx,rx}_queue in mt76 module

Browse Source 
Move mt76x02_init_tx_queue and mt76x02_init_rx_queue in mt76
module in order to be reused adding support for mt7603 driver
and remove duplicated code.
Squash mt76x02_init_tx_queue and mt76x02_init_rx_queue in
mt76_dma_alloc_queue
