[dpdk-dev] [PATCH v1 1/1] test/power: check cpuinfo cur freq before scaling cur freq

[Richael Zhuang <richael.zhuang@arm.com>]

For acpi_cpufreq and cppc_cpufreq, both cpuinfo_cur_freq and
scaling_cur_freq exist. For pstate, only scaling_cur_freq exists.
And value in scaling_cur_freq and cpuinfo_cur_freq may not be the
same. For acpi_cpufreq and cppc_cpufreq, we should check
cpuinfo_cur_freq. So here checking cpuinfo_cur_freq before
scaling_cur_freq to make sure it works for all cpufreq drivers.
