ACPI: CPPC: Add min and max perf register writing support

Currently writing of min and max perf register is deferred in
cppc_set_perf function. In CPPC guided mode, these registers needed to
be written to guide the platform about min and max perf levels. Add this support
to make guided mode work properly on AMD shared memory systems.
