arm64: dts: qcom: msm8916-samsung-j5-common: Add touchscreen 



J5 and J5X use an Imagis IST3038C touchscreen that is connected to
blsp_i2c5. Add it to the device tree.

MFD driver for SM5703 is unavailable at the moment, which is required
to power up the touchscreen on J5, so it's disabled on J5 for now.
