[CPUFREQ] powernow-k8: improve error messages

The most common error with powernow-k8 is an ACPI _PSS error
caused either by failure to load the ACPI processor module
or a bad parse of the _PSS object.  Make the error message
returned to the user in these situations more straightforward
and easier to understand.
