[RFC PATCH v2 40/69] KVM: Export kvm_is_reserved_pfn() for use by TDX

[isaku.yamahata@xxxxxxxxx]

From: Sean Christopherson <sean.j.christopherson@xxxxxxxxx>

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.
