jmcneill e184a4583b Add support for GPIO configuration via "FEX" scripts, in an attempt to
keep awin_device_register under control.

Board configuration scripts can be found here:
  https://github.com/linux-sunxi/sunxi-boards/blob/master/sys_config

You can compile them with the "fex2bin" tool found here:
  https://github.com/linux-sunxi/sunxi-tools

To use, copy the compiled FEX to your MS-DOS partition, load it with
U-Boot, and then tell the kernel where to find it with the "sysconfig="
boot option. For example, uEnv.txt on a Cubieboard2 might look like this:

  bootargs=root=ld0a sysconfig=0x43000000
  uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 43000000 cubieboard2.bin; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000
