This adds a command to connect or disconnect, and to switch the
PHY between A or B.
BUG=chrome-os-partner:52055
BRANCH=none
TEST=make buildall; test on Cr50
Using a test board with both PHYs plugged in, try the various
commands:
usb off
usb on
usb a
usb b
The on/off option connects and disconnects, the a/b option
switches between PHYs. You can see the state change on the
console, or by running dmesg on the host.
