MLK-18393 imx8: Check the eDMA channels and update DTB

Since M4 will arrange some eDMA channels to its partition, the A core
can't use them. We have to remove these eDMA channels from DTB dynamically.

Different like other resources, disabling the eDMA channels require to modify
the edma nodes by removing relevant registers, interrupts configurations, and
adjust dma channels number.

This patch searches the edma nodes from kernel DTB, checks the channels by
binding their registers base address with their resource IDs. Then update
the reg, interrupts, interrupt-names and dma-channels properties.
