Implement all the logic to get G2 hardware decoding HEVC frames.
It support up level 5.1 HEVC stream.
It doesn't support yet 10 bits formats or scaling feature.

Add HANTRO HEVC dedicated control to skip some bits at the beginning
of the slice header. That is very specific to this hardware so can't
go into uapi structures. Compute the needed value is complex and require
information from the stream that only the userland knows so let it
provide the correct value to the driver.

In order to be able to share the control hardware block between
VPUs use a syscon instead a ioremap it in the driver.
To keep the compatibility with older DT if 'nxp,imx8mq-vpu-ctrl'
phandle is not found look at 'ctrl' reg-name.

Introducing G2 hevc video decoder lead to modify the bindings to allow
to get one node per VPUs.
VPUs share one hardware control block which is provided as a phandle on
an syscon.
Each node got now one reg and one interrupt.

On boards where the only peripheral connected to PL0/PL1 is an X-Powers
PMIC, configure the connection to use the RSB bus rather than the I2C
bus. Compared to the I2C controller that shares the pins, the RSB
controller allows a higher bus frequency, and it is more CPU-efficient.

   - Fully serialize manager and worker creation, fixing races due to

   - Clean up some naming that had gone stale.

   - SQPOLL fixes.

   - Fix race condition around task_work rework that went into this
     merge window.

   - Implement unshare. Used for when the original task does unshare(2)
     or setuid/seteuid and friends, drops the original workers and forks
     new ones.

   - Drop the only remaining piece of state shuffling we had left, which
     was cred. Move it into issue instead, and we can drop all of that
     code too.

   - Kill f_op->flush() usage. That was such a nasty hack that we had
     out of necessity, we no longer need it.

   - Following from ->flush() removal, we can also drop various bits of
     ctx state related to SQPOLL and cancelations.

   - Fix an issue with IOPOLL retry, which originally was fallout from a
     filemap change (removing iov_iter_revert()), but uncovered an issue
     with iovec re-import too late.

   - Fix an issue with system suspend.

   - Use xchg() for fallback work, instead of cmpxchg().

   - Properly destroy io-wq on exec.

   - Add create_io_thread() core helper, and use that in io-wq and
     io_uring. This allows us to remove various silly completion events
     related to thread setup.

   - A few error handling fixes.

  This should be the grunt of fixes necessary for the new workers, next
  week should be quieter. We've got a pending series from Pavel on
