Change summaries:

300818 by adrian:
[gpio] add gpiospi to the gpio module.

300817 by adrian:
[spigen] add the userland ioctl API for spigen.

300816 by adrian:
[gpiospi] add debug option.

This was missing from the previous commit that introduced gpiospi.
It's required for it to build.

Only build gpio modules on armv6, until it's known that they can be built
succesfully on other arches.
