[PATCH 4/7] dt-bindings: dma: allwinner,sun50i-a64-dma: Add compatible for H616

[Chen-Yu Tsai <wens@kernel.org>]

From: Chen-Yu Tsai <wens@csie.org>

The DMA controllers found on the H616 and H618 are the same as the one
found on the H6. The only difference is the DMA endpoint (DRQ) layout.

Since the number of channels and endpoints are described with additional
generic properties, just add a new H616-specific compatible string and
fallback to the H6 one.

Signed-off-by: Chen-Yu Tsai <wens@csie.org>
