Perry Yuan cb817ec667 cpufreq: amd-pstate: show CPPC debug message if CPPC is not supported
Add CPU ID checking in case the driver attempt to load on systems where
CPPC functionality is unavailable. And the warning message will not
be shown if CPPC is not supported.

It will also print debug message if the CPU has no CPPC support that
helps to debug the driver loading failure issue.
