[XEN PATCH v1 07/15] x86/p2m: guard vmx specific ept functions with CONFIG_VMX

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

From: Xenia Ragiadakou <burzalodowa@xxxxxxxxx>

The functions ept_p2m_init() and ept_p2m_uninit() are VT-x specific.
Do build-time checks and skip these functions execution when !VMX.

No functional change intended.
