ARM: dts: msm: optimize CPR configurations for msm8226-v1/v2 and msm8926
Move common CPR regulator configurations for msm8226-v1, msm8226-v2, and
msm8926 into msm8226-regulator.dtsi. Move msm8226-v1 specific
configurations into msm8226-v1.dtsi since most CPR configuration parameters
are common between msm8226-v2 and msm8926.
