sn5s330: Add support for Vbus detection.
The SN5S330 has support for detecting when Vbus is present on a port.
This commit simply adds an API to query the PPC.
BUG=None
BRANCH=None
TEST=`make -j buildall`.
TEST=Flash a board with the SN5S330, with some extra code, verify that
Vbus can be detected with this API.
