platform/x86/amd/pmf: Add support SPS PMF feature


SPS (a.k.a. Static Power Slider) gives a feel of Windows performance
power slider for the Linux users, where the user selects a certain
mode (like "balanced", "low-power" or "performance") and the thermals
associated with each selected mode gets applied from the silicon
side via the mailboxes defined through PMFW.

PMF driver hooks to platform_profile by reading the PMF ACPI fn9 to
see if the support is being advertised by ACPI interface.

If supported, the PMF driver reacts to platform_profile selection choices
made by the user and adjust the system thermal behavior.
