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 this issue, add the rules of pinmux and pincfg in each child node
and grandchild node.
