soc/intel/skl: replace conditional on dt option reading CPUID for CPPC
Check ISST (Intel SpeedShift) availability via CPUID.06H:EAX[7], instead
of relying on the devicetree option `speed_shift_enable`, that is going
to be dropped.
Test: GCPC and _CPC entries still get generated on Supermicro X11SSM-F
