formfactor: detect USB HID keyboard and touch screen
The new machconfig probes USB keyboard and touch screen, and then sets HAVE_* variables according to detection. Detectable devices: USB HID keyboards (Generic Desktop) USB HID touch screens (Digitizer) Note: The intention is to have a way to provide initial formfactor settings in a boot procedure. That means supported keyboard and touch screen must be connected before machconfig runs. Any new connection or disconnection won't be detected until machconfig is executed again. Limitation: There could be some USB HID devices presents more than one usage in a single descriptor. We will add support once such device emerges. Some platforms may have _virtual_ devices provided by BIOS. It will cause false detection when they are presented as types we supported. We can add black list logic when it becomes a big concern.
