From: Chen-Yu Tsai <wens@xxxxxxxx>
The DMA controllers found on the H616 and H618 are the same as the one
found on the A100. The only difference is the DMA endpoint (DRQ) layout.
Add a device node for it, and add DMA channels for existing peripherals.
Signed-off-by: Chen-Yu Tsai <wens@xxxxxxxx>

Changes since v1:
- Fall back to A100 instead of H6
- Add DMA channels for r_i2c
