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.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/pinctrl/pinctrl.yaml:45:8: [warning] wrong indentation: expected 8 but found 7 (indentation)

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240123-mbly-clk-v3-3-392b010b8281@bootlin.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
