ppc: Add API to set Vbus source ILIM.
The PPC needs to update its Vbus source current limits whenever our
policy changes on the PD ports. This commit simply adds and API to do
so.
BUG=None
BRANCH=None
TEST=With some extra code to enable 3A out, flash zoombini; Plug in a PD
device to a port, verify that it gets 5V @ 3A. Plug in a second device,
verify that we re-send new source caps of 5V @ 1.5A.
TEST=Repeat above for meowth.
