drivers: led: add driver for PWM LEDs This driver supports the PWM driven LEDs. The devices are created from the DT nodes with a compatible property matching "pwm-leds". For each child node a LED is created and its "pwms" phandle's node is used to retrieve the PWM configuration: channel, period and flags. If some of this properties are missing (it is the case for some PWM controllers), then reasonable default values are used. This driver implements the following LED API methods: - led_on - led_off - led_blink - led_set_brightness Signed-off-by: Simon Guinot <simon.guinot@seagate.com>
