Move mt76x02/mt7603 dma shared code in mmio.c/dma.c in order to be
reused adding support for mt7603 driver
Changes since v1:
- remove mt76_irq_enable/mt76_irq_disable
- move dma queue initialization in mt76_dma_alloc_queue
- move mt76_irq_enable call into the driver specific
inline functions

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