[PATCH 0/2] gpio: ixp4xx: Handle external clock output

The GPIO block on the very legacy IXP4xx GPIO can provide
a generated clock output on GPIO 14 and GPIO 15. This
provides a straight-forward solution with a flag for each
clock output.

More complicated solutions are thinkable, but I deemed them
overdesigned for this legacy SoC.
