s390/mm: define arch_get_mappable_range()

This overrides arch_get_mappabble_range() on s390 platform which will be
used with recently added generic framework.  It modifies the existing
range check in vmem_add_mapping() using arch_get_mappable_range().  It
also adds a VM_BUG_ON() check that would ensure that mhp_range_allowed()
has already been called on the hotplug path.
