'''Description:''' Query the physical address of a virtual address. Will always fetch the lowest page-aligned mapping that contains the provided physical address.
The returned BaseAddr is the virtual address of that page-aligned mapping, while PhysAddr is the physical address of that page. Size is the amount of continuous physical memory in that mapping.
