[ 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.
