Status led for fastboot mode [feature request]


I seems really odd that there is no led indicator for when the device is in fastboot mode, thrice I’ve spent hours wondering why the 960 didn’t show up on fastboot devices just to find out that it was simply switched off from the mains…
and today i found out that my hikey 960 was left on for three days on fastboot mode and i had no idea about it.
Since there is no hard wired “Power LED” it would be a good idea to have on implemented in software for various modes since we have a bunch of on-board leds already.
