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.
