We are trying to get rid of the legacy LED API and this is one of the
last users.
As far as I understood from the code, only one LED is controllable and
it is a GPIO led. When initializing the LED, it is always enabled
regardless of the passed argument, same for the mask.
In addition, the LED is used as a BOOT LED.
To keep the same behavior, a GPIO driver should be written, then add a
gpio-leds node which makes use of a GPIO from said driver, add the
/options/u-boot/boot-led property pointing at this new GPIO LED node and
then enable CONFIG_LED as well as CONFIG_LED_BOOT. This should result in
the same behavior using the modern framework.
