x86/cpufeatures: Add X86_FEATURE_AMD_HETEROGENEOUS_CORES
CPUID leaf 0x80000026 advertises core types with different efficiency
rankings.
Bit 30 indicates the heterogeneous core topology feature, if the bit
set, it means not all instances at the current hierarchical level have
the same core topology.
This is described in the AMD64 Architecture Programmers Manual Volume
2 and 3, doc ID #25493 and #25494.
