amd_iommu: Fix kvm_enable_x2apic link error with clang in non-KVM builds
Commit b12cb3819 (amd_iommu: Check APIC ID > 255 for XTSup) throws
linking error for the `kvm_enable_x2apic` when kvm is disabled
and Clang is used for compilation.
This issue comes up because Clang does not remove the function callsite
(kvm_enable_x2apic in this case) during optimization when if condition
have variable. Intel IOMMU driver solves this issue by creating separate
if condition for checking variables, which causes call site being
optimized away by virtue of `kvm_irqchip_is_split()` being defined as 0.
Implement same solution for the AMD driver.
