I am even wondering if we should be adding any of the devm_* helpers
for now to be honest. Even for the other one we have only one user.
Them major user of the OPP core is the CPU subsystem and it is never
going to use these devm_* helpers as the CPU device doesn't get bound
to a driver, it is rather a fake platform device which gets the
cpufreq drivers probed. So the only users of these devm_* helpers is
going to be non-CPU devices. Considering that we have only one user
right now, it may be better to just fix it instead of adding any of
the devm_* helpers.
