[LEDE-DEV] [PATCH 2/2] base-files: support usbport LED trigger

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This adds ucidef_set_led_usbport function that can be called by target
board.d files. Example usage:
ucidef_set_led_usbport "usb" "bcm53xx:blue:usb" "usb1-port1" "usb2-port1"

List of available ports can be fetched using:
ls -d /sys/bus/usb/devices/*/*-port*
or
echo usbport > trigger
ls ports/
