kernel: allow multiple LEDs for panic blinks #1036
Pull Request Overview
This is motivated by Signpost, where some boards would like to blink

Maybe not. Having a standard panic blink format (the red led if one exists, or the first led if not) makes it easier to ask "Is the red led blinking in a two pulse pattern?" (or something like that) when helping someone to debug, without having to look up for each board what the panic led configuration is on that particular board.
For the signpost case I think this PR clearly makes sense.
