[Patch V2 3/6] QuarkPlatformPkg: Set PcdSpeculationBarrierType to CPUID

["Michael D Kinney" <michael.d.kinney@intel.com>]

Set PcdSpeculationBarrierType to use CPUID instead of the
default LFENCE in the BaseLib function SpeculationBarrier().
LFENCE requires SSE2, and Quark platforms do not support
SSE2.
