[RFC PATCH 33/67] KVM: Export kvm_is_reserved_pfn() for use by TDX

[isaku . yamahata]

From: Sean Christopherson <sean.j.christopher...@intel.com>

TDX will use kvm_is_reserved_pfn() to prevent installing a reserved PFN
int SEPT.  Or rather, to prevent such an attempt, as reserved PFNs are
not covered by TDMRs.
