when turbo is enabled or disabled, the frequency is set to a low non-turbo
frequency, so we need to set to the frequency expected by the test before
checking.

With the intel_pstate driver and turbo enabled, indexing is slightly
different to normal, so to get the test to work properly, enable
turbo at the start.

With the intel_pstate driver and turbo enabled, the top frequency in
the frequency array is the P1+1, i.e. 2300001, whereas the frequency
shown in scaling_cur_freq could be a lot higher.
This patch adds a flag to the check_cur_freq function so that we can
specify if a frequency is greater than expected (turbo mode), in which
case the check should be successful.

Different drivers present the current cpu core frequency in different
sysfs files. Some present it in cpuinfo_cur_freq, some in scaling_cur_freq,
and some actually present it in both.
This patch attempts to open one, if that fails, tries the other.

The value in "/sys/.../cpuinfo_cur_freq" may not be exactly the
same as what was set. For example, if "2400000" is written to
"/sys/.../cpufreq/scaling_setspeed" to set the frequency, then the
value in "/sys/.../cpuinfo_cur_freq" may be "2401222". So need to
round the value.

For some platforms the newly-set frequency may not be effective
immediately. If we didn't get the right value from cpuinfo_cur_freq
immediately, add 10ms delay each time before rechecking until
timeout.
From our test, for some arm platforms, it requires up to 700ms when
going from a minimum to a maximum frequency. And it's not the
driver/software issue.
