Fabio Baltieri 3d593b6e80 pwm: pwm-cros-ec: Add channel type support
Add support for EC_PWM_TYPE_DISPLAY_LIGHT and EC_PWM_TYPE_KB_LIGHT pwm
types to the PWM cros_ec_pwm driver. This allows specifying one of these
PWM channel by functionality, and let the EC firmware pick the correct
channel, thus abstracting the hardware implementation from the kernel
driver.

To use it, define the node with the "google,cros-ec-pwm-type"
compatible.
