Alexander Gordeev 70caac180f s390/maccess: rework absolute lowcore accessors ...

[ Upstream commit ed0192bc644f3553d64a5cb461bdd0b1fbae3fdf ]

Macro mem_assign_absolute() is able to access the whole memory, but
is only used and makes sense when updating the absolute lowcore.
Instead, introduce get_abs_lowcore() and put_abs_lowcore() macros
that limit access to absolute lowcore addresses only.
