s390 updates for 5.17 merge window

- add fast vector/SIMD implementation of the ChaCha20 stream cipher,
  which mainly adapts Andy Polyakov's code for the kernel

  out its status

- fix race in page table release code, and and lots of documentation

- remove uevent suppress from cio device driver, since it turned out
  that it generated more problems than it solved problems

s390/dasd: use default_groups in kobj_type

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the s390 dasd sysfs code to use default_groups field
which has been the preferred way since commit aa30f47cf666 ("kobject:
Add support for default attribute groups to kobj_type") so that we can
soon get rid of the obsolete default_attrs field.
