google/chromeec: Add common infrastructure for boot-mode switches
Instead of defining the same functions for reading/clearing boot-mode switches from EC in every mainboard, add a common infrastructure to enable common functions for handling boot-mode switches if GOOGLE_CHROMEEC is being used. Only boards that were not moved to this new infrastructure are those that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific mechanism for reading boot-mode switches. BUG=None BRANCH=None TEST=abuild compiles all boards successfully with and without ChromeOS option.
