This patchset adds a very simple kernel panic LED trigger,
by hooking into panic_blink. I've tested this trigger on
ARM Armada XP OpenBlocks AX3-4 machine.

The trigger is then used to replace the open-coded panic_blink
usage in GTA02 board.

Note that I don't have a GTA02 board, so the last patch is only
built tested.

ARM: configs: Enable panic LED trigger on s3c2410
ARM: s3c24xx: Use the panic LED trigger for GTA02
