Move cold reset handling from servo to power_state_controller.
New board support for Link will use cold_reset, but the usage pattern
will be slightly different. This moves cold_reset from class Servo to
power_state_controller and provides hooks to accommodate board
differences.
Ths change also includes minor additional refactoring and cleanup.
