Subject: [PATCH] arm64: dts: uniphier: add syscon property for UniPhier sound system

This patch adds syscon property for specifying soc-glue core into
device-tree of LD11/LD20 SoC.

Currently, soc-glue core is used for changing the state of S/PDIF
signal output pin to signal output state or Hi-Z state.

Please split PXs2 changes into a different patch.

Remove unneeded blank line between properties.

Could you use 'soc_glue', please?
I saw a conflict between 'sg' and 'soc_glue' among Socionext engineers
and I prefer the latter.
