[PATCH v2] dt-bindings: leds: Document "rc-feedback" trigger

[Heiko Stuebner]

Document the "rc-feedback" trigger which is used to control LEDs by
remote control device activity. This is an existing trigger used in
existing DTs, document it so validation of those DTs would pass.

It was originally introduced into the Linux kernel in 2013 with
commit 153a60bb0fac ("[media] rc: add feedback led trigger for rc keypresses")
