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.

Note: The companion AST2700 SoC0 pinctrl series modifies the same
binding and has been applied to pinctrl/for-next. Linus Walleij noted
for the equivalent SoC0 MFD patch that it should be applied through the
MFD tree by Lee Jones, providing an Acked-by in the process [1]. The
same routing applies to this patch.
