Instead of using a global variable with the current guest type or the XENFEAT_auto_translated_physmap Xen feature, use the already existing X86_FEATURE_XENPV for guarding PV mode specific code.
This has the advantage of compile time code elimination in case of the kernel having been configured without CONFIG_XEN_PV, and the usage of static-keys for selecting the correct code path otherwise.
