Subject: [PATCH 2/5] KVM: x86: Clean up redundant CC macro definition

From: Like Xu <likexu@...cent.com>

With the exception of drivers/dma/pl330.c, the CC macro is defined and used
in {svm, vmx}/nested.c, and the KVM_NESTED_VMENTER_CONSISTENCY_CHECK
macro it refers to is defined in x86.h, so it's safe to move it into x86.h
without intended functional changes.
