The AST2700 SoC integrates two interconnected SoC instances, each
managed by its own System Control Unit (SCU).

Allow the AST2700 SoC0 pin controller to be described as a child
node of the SCU by extending the compatible strings accepted by
the SCU binding.

There are no functional changes to the SCU binding beyond permitting
the AST2700 SoC0 pinctrl compatible string.
