i386: Propagate SGX CPUID sub-leafs to KVM
The SGX sub-leafs are enumerated at CPUID 0x12. Indices 0 and 1 are
always present when SGX is supported, and enumerate SGX features and
capabilities. Indices >=2 are directly correlated with the platform's
EPC sections. Because the number of EPC sections is dynamic and user
defined, the number of SGX sub-leafs is "NULL" terminated.
