Subject: [PATCH v3 18/18] ARM: dts: qcom: add ipq8065 dtsi

Many device are based on ipq8065 SoC. Ipq8065 is an evolution of the
ipq8064 SoC (also named ipq8064-v3.0 from qsdk) that has all the
improvement from ipq8064-v2.0 with the addition of a more powerful CPU
that can now be clocked to 1.7Ghz, a quicker L2 cache that can be
clocked to 1.4Ghz. It also shipped with more powerful regulators to
provide the required voltage to the CPUs and L2.
