The example for the CrOS EC PWM is incomplete and now generates a dtc
warning:
Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.example.dts:17.11-23.11:
Warning (unit_address_vs_reg): /example-0/cros-ec@0: node has a unit name, but no reg or ranges property
Fixing this results in more warnings as a parent spi node is needed as
well.
