PATCH v2 1/1 led: ALIX.2 LEDs driver

Driver for PC Engines ALIX.2 and ALIX.3 LEDs.

Signed-off-by Constantin Baranov <[email protected]>

Changes from previous version:
- rename from LEDS_ALIX to LEDS_ALIX2, because driver may not work with possible future ALIX boards
- scan BIOS area (000f0000:000fffff) to ensure that current system is ALIX.2/3
- add module parameter 'force' to allow registering LEDs without BIOS test (e.g. if stock BIOS was upgraded)

What kind of ninja mutant system is that? Can't you identify it using DMI or something?

This is minimalistic single board system. It doesn't contain any specific PCI devices. Linux says "DMI not present or invalid."

I has no ideas how to identify ALIX, except the Richard's idea of scanning BIOS.
