Subject: [PATCH v3 03/18] ARM: dts: qcom: add missing rpm regulators and cells for ipq8064

Add cells definition for rpm node and add missing regulators for the 4
regulator present on ipq8064. There regulators are controlled by rpm and
to correctly works gsbi4_i2c require to be NEVER disabled or rpm will
reject any regulator change request.
