ARM: dts: qcom: Add support for Samsung Galaxy Tab 4 10.1 LTE (SM-T535)

Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T535) LTE tablet
based on the MSM8926 platform.

The common dtsi is also modified to describe the widest constraints,
which required modifications to the matisse-wifi dts.
