Subject: [PATCH v2 1/2] 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.
