Wiring up the USB hub to the connectors allows us to gain the proper 'connect_type' and 'removable' values in sysfs for the USB devices on sc7180 trogdor devices. These two patches are split off of a larger series[1] so they can land faster and because we've come to the conclusion that the DisplayPort path is going to connect to the cros-ec-typec node, not the usb-c-connector node. The first patch adds the pogo pin binding to describe the detachable keyboards found on some trogdor devices (actually strongbad). The second patch is the dts changes required to wire up all the USB stuff. This is sufficient to set the sysfs properties for USB devices so that the builtin USB webcam is considered "fixed" or hard-wired while devices plugged into the connectors or the keyboard are considered "removable" or hotpluggable.
