soc: qcom: msm_perf: use cpuinfo.min/max while adding freq qos request 



cpuinfo.min_freq/max_freq gives the real min/max frequencies available.
whereas policy min/max offer current min/max of the policy, which
may be the desired values set by any other client like msm_perf or
even a postboot setting. This can potentially limit min/max
frequencies ranges.
