platform/x86/amd/pmf: Add support for notifying Smart PC Solution updates
The APMF function 14 (Notify Smart PC Solution Updates) allows the BIOS
(AMD/OEM) to be informed about the outputs of custom Smart PC policies.
Enhance the PMF driver to invoke APMF function 14 when these custom policy
outputs are triggered.
