There is no need to have a special case for CPU0 when converting the
page-table virtual address into a physical address. The helper
virt_to_maddr() is able to translate any address as long as the root
page-tables is mapped in the virtual address. This is the case for all
the CPUs at the moment.

So use the same BUG_ON() regardless the CPU.

I went back through the conversation in [1] regarding the issue when
loading Xen below 2MB on Arm32. The example provided is wrong because to
find the physical address, we need to add 'phys_offset', not substract.

So I removed the comment regarding the code was buggy.

Stefano, can you confirm that you are happy with the new commit message?
