servo: add prefix logic to set/get/has_control

With the new servod, there will be a notion of prefixes for controls.
servo should own that logic to some degree i.e. expose discovery of
devices & their prefixes, and allow to run controls based on prefixes
and control name.

This change adds the logic to run controls by providing prefix and
control-name separately, and glues it together internally. The
subsequent CL uses this to query servo firmware versions properly.

BUG=chromium:1009616
TEST=see subsequent CL
