google/chromeec: Add common infrastructure for boot-mode switches

Browse Source 
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.
