boot_phys_offset stores the physical offset (PA-VA), is calculated in

There is no point in using it given that we can ask MMU to translate
a VA for us using e.g. virt_to_{mfn,maddr}. Drop usage of these
variables from the C world.
I think the code is a remanant of when Xen would be relocated to the top
of the RAM. In this case, virt_to_mfn() would not have worked.
This was removed by f60658c6ae47 ("xen/arm: Stop relocating Xen") and I
don't expect the relocation code to be re-introduced. So...
