The 3rd LED on this board is something like a power-led, it is on all the
time. With this change to the leds-wrap driver it is possible to use this
LED too.

As discussed on LKML some notion of 'function' is needed in
LED naming. This patch adds this to the documentation and
standardises existing LED drivers.

A driver for the PCEngines WRAP boards (http://www.pcengines.ch), which are
very similar to the Soekris net4801 (same NS SC1100 geode reference
design).
The LEDs on the WRAP are on different GPIO lines and I have modified and
copied the net48xx error led support for this. It also includes support
for an "extra" led (in addition to error). The three LEDs on the WRAP are
at GPIO lines 2,3,18 (WRAP LEDs from left to right). This driver gives
access to the second and third LEDs by twiddling GPIO lines 3 & 18.
Because these boards are so similar to the net48xx, I basically sed-ed that
driver to form the basis for leds-wrap.c. The only changes from
leds-net48xx.c are:
- #define WRAP_EXTRA_LED_GPIO
- name changes
- duplicate relevant sections to provide support for the "extra" led
- reverse the various *_led_set values. The WRAP is "backwards" from the
net48xx, and these needed to be updated for that.
