Subject: [PATCH] arm64: dts: allwinner: a64: Disable SPDIF by default

As of v5.7-rc2, Linux now prints the following message at boot:

  [   33.848525] platform sound_spdif: deferred probe pending

This is because &sound_spdif is waiting on its DAI link component
&spdif to probe, but &spdif is disabled in the DTS. Disable the
audio card as well to match.
