Power cycle USB ports trough permission_broker
Fizz (and future CfM devices) now have firmware that allows the root
USB hub to power cycle individual ports trough ACPI. For security
purposes, the actual power cycling is delegated to permission_broker
via DBus.
Guado will still have to use it's GPIO hack since its firmware doesn't
support power cycling trough the hub.

TEST=Verify that `echo "<3>uvcvideo: Failed AUTOTEST" >> /dev/kmsg`
will trigger huddly-monitor to power cycle a connected Huddly.
