leds: gpio: Support the "panic-indicator" firmware property
Calling a GPIO LEDs is quite likely to work even if the kernel has paniced, so they are ideal to blink in this situation. This commit adds support for the new "panic-indicator" firmware property, allowing to mark a given LED to blink on a kernel panic.
