suzy-qable advertises 1.5A, but its actual capability depends on the host USB port it is attached to. Since suzy-qable is ubiquitous and other DTS sources may behave in the same way, ramp the input current limit in order to find a reasonable maximum. BUG=chromium:770296 BRANCH=None TEST=Attach suzy-qable to kevin and reef, verify that neither OCs and EC console via cr50 is available on reef. Also verify donette chargers kevin at 3A and does not ramp.
