Downstream kernel parses resource names based on pm8950-rpm-regulator.dtsi
in such file qcom,resource-name takes three values: smpa,ldoa and clk0.
First appearance of RWSC/RWSM point to msm-4.4 kernel
which is way newer than what this platform was shipped with (msm-3.10).
For the max_state downstream code limit value to TURBO inside dts
with only one turbo_high being placed in msm-thermal bindings.
One of effects of requesting TURBO_HIGH vote is rebooting of device
which happens during voting inside WCNSS/IRIS,
this behavior was observed on LeEco S2 smartphone.
Fix regulator setup and drop unused resources.
