[RFC 03/10] x86/p2m: guard vmx specific ept functions with INTEL_VMX

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

The functions ept_p2m_init(), ept_p2m_uninit() and p2m_init_altp2m_ept() are
VT-x specific.
Implement them as unreachable static inline functions when !INTEL_VMX.

No functional change intended.
