This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOs
Driver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here also
This driver is inspired by leds-net5501.c by Alessandro Zummo.
Ideally, leds-net5501.c should also be moved to platform/geode.
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.

Add CE4100 platform support. CE4100 needs early setup like
moorestown.

x86 has finally arrived in the embedded nightmare and will rapidly
grow SoC platform support in various flavours. So we need a place for
the platform support files. That also allows us to clean up the
dumpground which arch/x86/kernel has become over time.
