platform/x86/amd/pmf: store BIOS output values for user-space metrics via util IOCTL

Browse source

Add a bios_output[] to amd_pmf_dev struct and store the latest values for
BIOS output policies when applying PMF policies. This enables the AMD PMF
util layer to expose these BIOS outputs alongside selected thermal and
power metrics to user space via /dev/amdpmf_interface and a new IOCTL,
supporting real-time monitoring tools such as SystemDeck.
