s390/dcssblk: Add DAX support
With ZONE_DEVICE now available for s390, struct pages can be allocated
for proper DAX support in dcssblk driver via devm_memremap_pages().
Adding struct pages for a range requires that the range is aligned to
SUBSECTION_SIZE, which is defined as 2 MB in common code. Therefore,
only enable DAX support and allocate struct pages for DCSS ranges that
are aligned to 2 MB.
