faft: Support EC hostevent in Chrome EC class
We set the EC hostevent to emulate the keyboard recovery combination
(Esc+Refresh+Power) has been pressed. Such that on EC reboot, it triggers
the same recovery path.
This CL wraps the underlying hostevent command into a method. It makes
the hostevent more easy to be used without knowing any detail of the EC
command.
