Add fb-powerctrl to Facebook Tiogapass
Added a new module fb-powerctrl to comtrol host power. It
includes power-util which controls power on and off of
given host server.
Tested: Build Facebook TiogaPass board and load on the
target hardware. Ensured that power on and off features
works as expected.
