ASoC: sun4i-spdif: Fix requirements for H6

When the H6 was added to the bindings, only the TX DMA channel was
added. As the hardware supports both transmit and receive functions,
the binding is missing the RX DMA channel and is thus incorrect.
Also, the reset control was not made mandatory.

Add the RX DMA channel for SPDIF on H6 by removing the compatible from
the list of compatibles that should only have a TX DMA channel. And add
the H6 compatible to the list of compatibles that require the reset
control to be present.
