[RESEND PATCH 07/32] i386: Add SGX CPUID leaf FEAT_SGX_12_0_EAX |

From: Sean Christopherson <sean.j.christopherson@intel.com>
CPUID leaf 12_0_EAX is an Intel-defined feature bits leaf enumerating
the CPU's SGX capabilities, e.g. supported SGX instruction sets.
Currently there are four enumerated capabilities:
- SGX1 instruction set, i.e. "base" SGX
- SGX2 instruction set for dynamic EPC management
- ENCLV instruction set for VMM oversubscription of EPC
- ENCLS-C instruction set for thread safe variants of ENCLS
