Add support for the Waveshare 1024x600 "C" Rev2.1 7" IPS Capacitive Touch
Screen LCD with HDMI interface:

	http://www.waveshare.com/7inch-HDMI-LCD-C.htm
	http://www.waveshare.com/wiki/7inch_HDMI_LCD_(C)

This product works "out of the box" with the Raspberry Pi. Simply connect
the provided HDMI and USB cables between the two devices. The touch<=>mouse
integration works automatically.

Tested with a Raspberry Pi 3, with a 32-bit raspberrypi3 build.
