Add semi-mt support. Kernel drivers for 'semi-mt' devices, such as the Synaptics profile sensor, do not provide a pressure value with their semi-mt slots. Instead, they report a single pressure value via ABS_PRESSURE. So, if the device's INPUT_PROP_SEMI_MT bit is set we use the ABS_PRESSURE value to set the height/width of all plotted circles. BUG=chromium-os:24277 TEST=mtplot And see if the touch events could be drawn on Cr-48. Change-Id: I4c3d564fc7fd902b7cdae0ac5850730f07ffde86
