cpufreq: amd-pstate: Allow users to write 'default' EPP string
The EPP string for 'default' represents what the firmware had configured
as the default EPP value but once a user changes EPP to another string
they can't reset it back to 'default'.
Cache the firmware EPP value and allow the user to write 'default' using
this value.
