arm64: dts: qcom: msm8916-huawei-g7: Add touchscreen 



The Huawei Ascend G7 has a Synaptics "C199HW-006" touchscreen,
supplied by pm8916_l17 and pm8916_l16. Add it to the device tree
and reduce the maximum allowed voltage for pm8916_l16 to 1.8V since
we really should not use more for an I/O supply.
