This commit removes the report service from the usb_webcam pkg, which
was used to enable or disable the webcam driver. The on/off state is
instead controlled by the presence of a capture client. That is, once a
capture client appears, the webcam driver is started. Vice versa, once
no capture client exists, the webcam driver is removed automatically.
Internally, the detection of presence of a capture client is based on
nitpicker's 'displays' report, which is consumed as input of the
rom_filter, which in turn generates the configuration of a dynamic sub
init.
