[PATCH] dt-bindings: leds: common: add disk write/read and usb-host

[Corentin Labbe <clabbe@baylibre.com>]

The triggers enum misses 3 cases used by gemini DT.
usb-host was added via commit 0cfbd328d60f ("usb: Add LED triggers for USB activity")
so we add also as valid trigger usb-gadget which was added along in this
commit.

disk-read/disk-write were added by commit d1ed7c558612 ("leds: Extends disk trigger for reads and writes")
