arm64: dts: tqma8mpql-mba8mpxl: Configure multiple queues on eqos

The MBa8MPxL mainboard has an integrated PHY connected to the EQOS
ethernet controller which can support up to five queues. Configure
these queues in the same manor as done on the imx8mp-evk.

Setting DMA to threas mode is necessary to prevent FIFO overflows, see
commit 0bc3e333a0c82 ("arm64: dts: imx8mp-evk: configure multiple queues
on eqos")
