cpufreq/amd-pstate: Add support for raw EPP writes
The energy performance preference field of the CPPC request MSR
supports values from 0 to 255, but the strings only offer 4 values.
The other values are useful for tuning the performance of some
workloads.
Add support for writing the raw energy performance preference value
to the sysfs file. If the last value written was an integer then
an integer will be returned. If the last value written was a string
then a string will be returned.
