platform/x86/amd/pmf: Extend custom BIOS inputs for more policies

The existing amd_pmf driver is limited to supporting just two custom BIOS
inputs. However, with the updates to the latest PMF TA, there's a
requirement to broaden this capacity to handle 10 inputs, aligning with
the TA firmware's capabilities.

The necessary logic should be implemented to facilitate this expansion of
functionality.
