amd/mendocino/root_complex: Throttle SOC during low/no battery
Use dynamic power and thermal configuration (DPTC) via ACPI ALIB calls
to throttle the SOC when there is no battery or critically low battery,
to enable the SOC to boot without overwhelming the AC charger and
browning out.
DPTC is not enabled for low/no battery mode with this CL. It will be
enabled for Skyrim in a following CL.
