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.
