arm/dt: msm8226: Switch to SPM control of PM8226 S2 regulator

Add a qcom,spm-regulator device node for the PMIC PM8226 SMPS 2
regulator which replaces the qcom,qpnp-regulator device node.
The S2 regulator supplies the four A7 processor cores.  Using
an spm-regulator device to control the S2 regulator ensures that
AVS is properly configured when the supply voltage is changed.
