ACPI: Disable the C2C3_FFH access mode HW has no MWAIT support
991528d7348667924176f3e29addea0675298944 (ACPI: Processor native C-states using MWAIT) started passing C2C3_FFH to _PDC to tell the BIOS that Linux supports MWAIT for deep C-states. However, we should first double check with the hardware that it actually supports MWAIT before potentially exposing a BIOS bug of an MWAIT _CST on HW that doesn't support MWAIT.
