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.

Some boards have more than one USB port. In that case, there is a second
GPIO on the debug board to simulate a USB disconnection for those.
Add the option to describe both USB disconnect GPIOs using
"usb0_disconnect" and "usb1_disconnect" and change both of them
when disabling USB power.
In the future it might be useful to control them separately, but for now
this ensures that power to the board is cut properly when the board is
powered off.
"patternProperties" must be on the same indentation level as "properties",
otherwise it just defines a property called "patternProperties" in
cdba.yaml.
Also add additionalProperties: false, so properties not matching the regex
are actually disallowed and reported.
While the CDB Assist and QcomLT Debugboard is measuring voltage and
current on the DC jack directly in the backend, other backends and
further measurements can be performed using custom tooling.
Introduce support for invoking an external "status-cmd" to produce such
status updates.
The status command should on its stdout produce json-formatted status
updates following the same format as the cdba-server:
{"ts":%d.%03d, "name": {["mv"|"ma"]: %u}(, "name2": {["mv"|"ma"]: %u})*}
with the ts aquired using clock_gettime(CLOCK_MONOTONIC) and provided in
seconds and milliseconds since the first measurement.
