Documentation: amd-pstate: introduce new global sysfs attributes
The amd-pstate driver supports switching working modes at runtime.
Users can view and change modes by interacting with the "status" sysfs
attribute.
1) check driver mode:
$ cat /sys/devices/system/cpu/amd-pstate/status
2) switch mode:
`# echo "passive" | sudo tee /sys/devices/system/cpu/amd-pstate/status`
or
`# echo "active" | sudo tee /sys/devices/system/cpu/amd-pstate/status`
