[ Upstream commit afacb21834bb02785ddb0c3ec197208803b74faa ]
It doesn't make sense to register the panic notifier if creating the
panic trigger failed.

This commit adds a new led_cdev flag LED_PANIC_INDICATOR, which
allows to mark a specific LED to be switched to the "panic"
trigger, on a kernel panic.
This is useful to allow the user to assign a regular trigger
to a given LED, and still blink that LED on a kernel panic.

This commit introduces a new LED trigger which allows to configure
a LED to blink on a kernel panic (through panic_blink).
Notice that currently the Openmoko FreeRunner (GTA02) mach code
sets panic_blink to blink a hard-coded LED. The new trigger is
meant to introduce a generic mechanism to achieve this.
