The ChromeOS Embedded Controller exposes an LED control command.
Expose its functionality through the leds subsystem.
The LEDs are exposed as multicolor devices.
A hardware trigger, which is active by default, is provided to let the
EC itself take over control over the LED.
The driver is designed to be probed via the cros_ec mfd device.
