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. Reviewed-by:Hans de Goede <hdegoede@redhat.com> Signed-off-by:
