Commit 054a3ef6 ("cpufreq: qcom-hw: Allocate qcom_cpufreq_data
during probe") moved getting memory resource and iomap from
qcom_cpufreq_hw_cpu_init() to the probe function, however it left
untouched cleanup in qcom_cpufreq_hw_cpu_exit().

During device unbind this will lead to doule release of resource and
double iounmap(), first by qcom_cpufreq_hw_cpu_exit() and second via
managed resources:

  resource: Trying to free nonexistent resource <0x0000000018593000-0x0000000018593fff>
