dt-bindings: mfd: aspeed,ast2x00-scu: Support AST2700 SoC1 pinctrl

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

Allow the AST2700 SoC1 pin controller to be described as a child
node of the SCU by extending the compatible strings accepted by
the SCU binding.

There is no functional change to the SCU binding beyond permitting
the aspeed,ast2700-soc1-pinctrl compatible string.
