Subject: [PATCH 4/4] arm64: dts: address cros-ec-pwm channels by type
Update various cros-ec-pwm board definitions to address the keyboard and
screen backlight PWM channels by type rather than channel number. This
makes the instance independent by the actual hardware configuration,
relying on the EC firmware to pick the right channel, and allows
dropping few dtsi overrides as a consequence.
Changed the node label used to cros_ec_pwm_type to avoid ambiguity about
the pwm cell meaning.
