sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supported
The processor P_BLK doesn't support throttling. This behaviour could be emulated with SMM, but instead just update the FADT to indicate no support for legacy I/O based throttling using P_CNT. We have _PTC defined in SSDT, which should be used in favour of P_CNT by ACPI aware OS, so this change has no effect on modern OS. Drop all occurences of p_cnt_throttling_supported and update autoport to not generate it any more.
