Plankton: Support DFU mode
This includes:
- Enabling SBU path for debug USB usage in USB mode (not in DP mode)
- Add a console command to enable DFU mode for lab devices. This
requires the additional Silego chip on the device.
BRANCH=None
BUG=None
TEST=Hook up a Ryu with the additional Silego chip. Issue 'dfu' command
and see DFU device in 'lsusb' output. Issue the command again and the
device goes away.
