soc/amd: factor out common get_pstate_core_power implementation

Browse Source 
Now that all get_pstate_core_power implementations in each SoC's acpi.c
file is identical, factor it out into a common implementation. This
implementation will also work for Stoneyridge which isn't using the
common P state code yet.
