x86: geode: New PCEngines Alix system driver
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.

+ ---help---
+ This option enables system support for the PCEngines ALIX.
+ At present this just sets up LEDs for GPIO control on
+ ALIX2/3/6 boards. However, other system specific setup should
+ get added here.
+
+ Note: You must still enable the drivers for GPIO and LED support
+ (GPIO_CS5535 & LEDS_GPIO) to actually use the LEDs
+
+ Note: You have to set alix.force=1 for boards with Award BIOS.
