led-trigger: Allow multiple led triggers of the same type
We used to have a static array of trigger types which, allows only one led
per trigger. While this is enough for panic and heartbeat, it falls short when
multiple leds are associated to the default-on trigger. The default-on trigger
is used to turn on a led statically from devicetree and may be used multiple
times.
This patch reworks the led triggers so that a trigger struct is allocated
dynamically when needed and put onto a list.
