This looks suspiciously like intel_ich_gpio_set.
Based on that, add board enables for the ASUS P5N-D and P5N-E SLI.
This was tested by Guillaume Poirier-Morency on a P5N-D:

i have made a few changes:
- renamed functions to our usual scheme
- marked the P5E (board enable) as not tested
- use a pointer to the config entry to access it instead of its index
the latter together with the goto makes the execution flow more obvious imho.
if anyone asks this is of course also

but i don't deserve it imo.
does the "if (!base)" check really make sense?
