Again why? I think the main goal should be to not mess up the normal
code. 

  #define virt_to_phys pkvm_virt_to_phys

Does that, we should be leaning into this pattern I think, not adding
unnecessary churn...

If anything is needed then it should be an iommu_pages function to
wrapper virt_to_phys() for use by iommu_pages uses but I'd rather
not..
