gpio-pca953x: add "drive" property
Galileo gen 2 has support for setting GPIO modes. Expose these
properties through the GPIO sysfs interface. This approach is
bit hacky, since it changes the interface semantics.
The original patch was by Josef Ahmad <josef.ahmad@linux.intel.com>
and made on top of kernel 3.8.
