[PATCH 1/4] arm64: dts: qcom: msm8998-lenovo-miix-630: enable touchscreen

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

There is no point in keeping touchscreen disabled, enable corresponding
i2c-hid device.

04F3:2608 Touchscreen as /devices/platform/soc@0/c179000.i2c/i2c-0/0-0010/0018:04F3:2608.0001/input/input1
04F3:2608 as /devices/platform/soc@0/c179000.i2c/i2c-0/0-0010/0018:04F3:2608.0001/input/input2
04F3:2608 as /devices/platform/soc@0/c179000.i2c/i2c-0/0-0010/0018:04F3:2608.0001/input/input3
04F3:2608 Stylus as /devices/platform/soc@0/c179000.i2c/i2c-0/0-0010/0018:04F3:2608.0001/input/input4
