xenheap_mfn_end is storing an MFN and not a physical address. Thankfully
xenheap_mfn_end is not used in the arm64 code. So drop it.
That's fine, but in that case I would prefer to move the definition of
xenheap_mfn_end under #ifdef CONFIG_ARM_32. In fact, there is another
assignment of xenheap_mfn_end few lines below in the arm64 version of
setup_mm: don't we need to remove that too?
The other xenheap_mfn_end contains valid mfn that point to the end and I
didn't want to #ifdef it because:
1) It complexify the code
2) All regions should be bound with start/end to simplify potential use.
