b055174e9e cpu: Add the matching rule "Model Name" when parsing cpuinfo 
This is to fix the error of running TestCpuInfo on Linux/long64. In loong64
/proc/cpuinfo, the model name is capitalize the first letter

feat: Setting the model name for arm based CPUs 
- Added arm model and model name as map.
- The modelName is set again according to the model value when the model name is empty.
- Based on lscpu source code.. https://github.com/util-linux/util-linux/blob/master/sys-utils/lscpu-arm.c

ee12f66e4d cpu, v3/cpu: use sysconf package instead of exec'ing getconf 
Currently, ClocksPerSec is determined by exec'ing getconf in func init,
i.e. on startup of every program importing the package. getconf might
not be present on some systems or is not executable by the current user.
To avoid this hard to control dependency, use the
github.com/tklauser/go-sysconf package which implements sysconf(3)
entirely in Go without cgo. The package is supported on all platforms
currently supported by the cpu and v3/cpu package of gopsutil.

fix panic when /proc/stat is empty 
don't really know why this would be the case, but I suppose there are
always edge-cases.

286927a039 Improve CPU identification for POWER processors 
Currently gopsutils fails to indentify the POWER processors family,
returning an almost empty Info() structure.

This patch improves the POWER identification without changing what is
available for x86.

3dc4e52844 Handle the case when the cpufreq sysfs does not exist 
* on virtualized host, this may happen.
* but we may have a value from parsing `/proc/cpuinfo`
* in this case, we do not return the error if we fail to extra
  a value from `cpufreq/cpuinfo_max_freq`

10a1ae2123 Standardize Mhz to mean maximum CPU frequency on Linux platform 
* resolve #249
* in `cpu_windows.go`, `Mhz` is the value of `MaxClockSpeed`
* on Linux platform, the `Mhz` value is extracted from `/proc/cpuinfo`
  which reflects the current clock speed; treat this as the fallback
  value instead
* read from `cpufreq/cpuinfo_max_freq` under sysfs to get the
  maximum clock speed for `Mhz`, just like for Windows platform
* also fix the path to `cpu.CoreID` value; the filename is `core_id`

123a6c9b0d Addressing frequency unit discrepancies 
* for Darwin, it is a minor tweak for readability: the value
  returned is in Hz, so using a variable named 'hz' makes more
  sense than 'mhz'
* for Linux, the unit is in kHz so we need to divide the value
  from `cpuinfo_max_freq` by 10^3 to get MHz (see
  cpu-freq/user-guide.txt of the kernel documentation)
