[PATCH] arm64: dts: imx8mm: Add node for SPDIF

[Adam Ford]

The i.MX8M Mini can support SPIDF which is very similar to the
IP used on the i.MX35.

This patch adds the SPIF node.

It should be in a patch series with previous micfil one, as it cannot be
applied independently.

Have a newline between nodes.
