wifi: mt76: mt792x: add tx_done ring to common DMA queue allocation

Browse Source 
Add a tx_done field to mt792x_dma_layout and extend
mt792x_dma_alloc_queues() to allocate the MT_RXQ_MCU_WA queue when
tx_done.ring_base is configured.

This is a preparation patch before enabling MT7928 PCIe support.
