Allow a pin controller device to have no address, therefore no unit address. The previous $nodename was enforcing a unit address, but scripts/dtc/checks.c enforced that names with unit addresses have reg or ranges: Warning (unit_address_vs_reg): .../pinctrl@0: node has a unit name, but no reg or ranges property Fix pinctrl.yaml to adopt a (pinctrl|pinmux)(-[a-z]+)? node name when neither reg nor ranges are required. Use [a-z]+ to avoid conflicts with pinctrl-consumer.yaml.
