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
