msm: cpufreq: Implement suspend/resume for cpufreq driver

Cpufreq suspend variable get's updated in kernel pm notifier
callback which gets called in process context. This will create
window where cpufreq governor may try to change the frequency
before suspend variable is updated while resume.

Define suspend/resume for cpufreq driver to update suspend variable
in atomic context.

Don't update the policy->cur upon cpufreq driver failure.
