net: stmmac: Disable flow ctrl for RX AVB queues and enable TX AVB queues

Ported fix from 5.4:
Flow control must be disabled for AVB enabled queues and TX
AVB queues must be enabled by setting BIT(2) of TXQEN.

Correct this by passing the queue mode to DMA callbacks
and by checking in these functions whether we are in AVB
performing the necessary adjustments.
