ec: Add a chipset reset hook
There are hooks for chipset power sequencing but not one to indicate
that the system has reset at runtime. Add a hook for this and
implement for lm4 and mec1322. The hook is notified on any platform
reset, including those that happen on the way into S3/S5 state.
There is a new config variable added because the hook is notified in
the interrupt handler and needs a deferrable function that needs to
be added to every board.
