The IP of QDMA ls1028/ls1043/ls1046/ is same as ls1021. So allow compatible
string fallback to fsl,ls1021a-qdma.

The difference is that ls1021a-qdma have 3 irqs, and other have 5 irqs.

Fix below CHECK_DTB warning.
arch/arm64/boot/dts/freescale/fsl-ls1046a-rdb.dtb: dma-controller@8380000: compatible: ['fsl,ls1046a-qdma', 'fsl,ls1021a-qdma'] is too long

- Combine depedent change to one patch.
