[RFC V1 3/8] cpufreq: imx: reuse dt_device.c to create cpufreq platform device

[Viresh Kumar]

We now have a common interface for create platform device required to probe
cpufreq-dt driver (and others as well). Lets create devices from dt_device.c
instead of platform specific code.

For imx, we are updating the blacklist instead of DT because the newer kernel
should be backwards compatible with older DT as well. We can update the
"compatible" property in DT but it wouldn't make a difference as we already have
imx in the blacklist.
