dt-bindings: pinctrl: uniphier: Add child node definitions to describe pin mux and configuration
In arch/arm/boot/dts/uniphier-pinctrl.dtsi, there are child nodes of pinctrl that defines pinmux and pincfg, however, there are no rules about that in dt-bindings. 'make dtbs_check' results an error with the following message: pinctrl: 'ain1', 'ain2', 'ainiec1', 'aout', 'aout1', 'aout2', ... ... 'usb2', 'usb3' do not match any of the regexes: 'pinctrl-[0-9]+' To avoid the issue, add the rules of pinmux and pincfg in each child node and grandchild node.
