    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.
