Convert qcom-nvmem-cpufreq to DT schema format, splitting it into
an OPP schema and a CPUFreq schema in the process.

In Certain QCOM SoCs like ipq8064, apq8064, msm8960, msm8974
that has KRAIT processors the voltage/current value of each OPP
varies based on the silicon variant in use.
The required OPP related data is determined based on
the efuse value. This is similar to the existing code for
kryo cores. So adding support for krait cores here.

Some Qualcomm SoCs have support for Core Power Reduction (CPR).
On these platforms, we need to attach to the power domain provider
providing the performance states, so that the leaky device (the CPU)
can configure the performance states (which represent different
CPU clock frequencies).

Not all Qualcomm platforms need to care about the speedbin efuse,
nor the value blown into the speedbin efuse.
Therefore, make the nvmem-cells and opp-supported-hw properties
optional.

qcom socs
The kryo cpufreq driver reads the nvmem cell and uses that data to
populate the opps. There are other qcom cpufreq socs like krait which
does similar thing. Except for the interpretation of the read data,
rest of the driver is same for both the cases. So pull the common things
out for reuse.

[niklas.cassel@linaro.org: split dt-binding into a separate patch and
do not rename the compatible string.]
