Don't make PPPS path exclusive to the driver USB control. Allow both to be used at the same time in case the setup uses both PPPS-hubs and driver-specific control. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
Extend laurent driver, allowing using a relay to control USB circuits. For example, the relay might be connected to the DIP switch on RB1 / RB2 boards. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

It is possible to use Laurent relays to control USB mode, e.g. by attaching the relay to the onboard DIP switch on RB1 / RB2 boards. Extend the driver to support such configurations.
