arm64: dts: allwinner: h6: Add RX DMA channel for SPDIF

Browse Source 
[ Upstream commit 7b59348c11f3355e284d77bbe3d33632ddadcfc2 ]

The SPDIF hardware found on the H6 supports both transmit and receive
functions. However it is missing the RX DMA channel.

Add the SPDIF hardware block's RX DMA channel. Also remove the
by-default pinmux, since the end device can choose to implement
either or both functionalities.
