gpio: decouple tristate gpio support from board ID

This deprecates TERTIARY_BOARD_ID. Instead, a board will set
    BOARD_ID_SUPPORT (the ones affected already do) which will set
    GENERIC_GPIO_SUPPORT and compile the generic GPIO library.
    The user is expected to handle the details of how the ID is encoded.

BUG=none
    BRANCH=none
    TEST=Compiled for peppy, nyan*, storm, and pinky
