dt-bindings: pwm: Fix cros-ec-pwm example dtc 'reg' warning
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.
