Add device tree node for touchscreen support on Colibri VF50. The
touchscreen functionality on VF50 uses the ADC channels of Vybrid
and some GPIOs. Also add pinctrl nodes for proper pinmux.

Minus rather than underscore should be used in node name.  And node name
should be generic.  "touchscreen" might be a good choice.
