Add support for calling deferred functions
This is a cleaner way of deferring work from interrupt-time to
task-time without requiring a task for each module which needs this.
Replaces/supersedes delayed hook notification, which didn't scale well
(since every function would have needed to be its own hook type).
BUG=chrome-os-partner:18473
BRANCH=none
TEST=boot system. plug/unplug AC power; notifies the host properly
