[RFC 06/10] x86/domain: guard svm specific functions with AMD_SVM

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

The functions svm_load_segs() and svm_load_segs_prefetch() are AMD-V specific
so guard their calls in common code with AMD_SVM.

Since AMD_SVM depends on HVM, it can be used alone.

No functional change intended.
