The "control-scb" region, contains the "tvs" temperature and voltage
sensors and the control/status registers for the system controller's
mailbox. The mailbox has a dedicated node, so there's no need for a
child node describing it, looking the syscon up by compatible is
sufficient.

v2:
add the control-scb syscon here too, since it doesn't have any children.
