nocturne: Remove internal pulls on PD interrupts.
On early revisions of nocturne, on board pullups were missing, therefore
the EC configured some internal pullups on the Type C interrupt pins.
On newer revisions, this has been fixed and external pullups are
stuffed.
This commit simply adds a board_quirks() function to remove the internal
pull up resistors on newer boards.
BUG=b:109937217
BRANCH=None
TEST=Change check to match current board revision, flash nocturne,
verify that internal pull ups were disabled.
