lynxpoint: Rework LP GPIO handling

This adds some macros for the common GPIO defines and drops
    the gpio number definition from each entry.  The end result
    is much easier to read.  The wtm2 mainboard gpio list is modified
    to use this.

Also fix a bug in the LP version of get_gpio() that was always
    returning zero due to a miscompare.
