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.

running on and reports it through the coreboot table to the rest of
the system.
