s390/mm: Create virtual memory layout structure
This is a preparatory rework to allow uncoupling virtual
and physical addresses spaces.
Put virtual memory layout information into a structure
to improve code generation when accessing the structure
members, which are currently only ident_map_size and
__kaslr_offset.
