mb/google/brya: Add GPIO table for nissa

Fill in the nissa baseboard GPIO table based on the nivviks P0 and
nereid P0 schematics. Also, add an override GPIO table for each of
nivviks and nereid.

The differences between nivviks and nereid are:
- WFC: nivviks has a MIPI WFC and nereid has a USB WFC, so the
  MIPI-related pins are overriden to NC on nereid.
- The DMIC pins and speaker I2S pins were swapped after nivviks P0. The
  baseboard reflects the new configuration, which will be used in
  nivviks P1 onwards, nereid, and future variants. For now, nivviks
  overrides the pins to the old configuration. Once nivviks P1 is
  released, this will need to be updated to handle both.

TEST=abuild -a -x -c max -p none -t google/brya -b nivviks
     abuild -a -x -c max -p none -t google/brya -b nereid
