OpenRISC updates for 5.9

A few patches all over the place during this cycle, mostly bug and
sparse warning fixes for OpenRISC, but a few enhancements too.  Note,
there are 2 non OpenRISC specific fixups.

Non OpenRISC fixes:

 - In init we need to align the init_task correctly to fix an issue with
   MUTEX_FLAGS, reviewed by Peter Z.  No one picked this up so I kept it
   on my tree.
 - In asm-generic/io.h I fixed up some sparse warnings, OK'd by Arnd.
   Arnd asked to merge it via my tree.

OpenRISC fixes:

 - Many fixes for OpenRISC sprase warnings.
 - Add support OpenRISC SMP tlb flushing rather than always flushing the
   entire TLB on every CPU.
 - Fix bug when dumping stack via /proc/xxx/stack of user threads.
