Rob Herring c3a2079828 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.

description: |
Google's ChromeOS EC PWM is a simple PWM attached to the Embedded Controller
(EC) and controlled via a host-command interface.
An EC PWM node should be only found as a sub-node of the EC node (see
Documentation/devicetree/bindings/mfd/cros-ec.txt).
