mt76: dma: move mt76x02_init_{tx,rx}_queue in mt76 module
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 Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
