This patch adds syscon property for specifying soc-glue core.

The soc-glue core is used for changing the state of S/PDIF signal
output pin to signal output state or Hi-Z state. After resetting of
SoC Hi-Z state is selected.

Currently, we set this mode in local changed U-Boot or some
bootloaders fixedly. This patch removes dependencies of bootloader
from UniPhier audio system driver.
