CI: New kernel for LAVA
This new kernel keeps closer track of mainline and should help with stability of Panfrost jobs.
The interesting commits include:
commit d12f8b7661b4514bb8af4cc61bac44c144a65a95 (HEAD -> v5.8-for-mesa-ci, tomeu/v5.8-for-mesa-ci)

drm/panfrost: Make sure MMU context lifetime is not bound to panfrost_priv
Jobs can be in-flight when the file descriptor is closed (either because
the process did not terminate properly, or because it didn't wait for
all GPU jobs to be finished), and apparently panfrost_job_close() does
not cancel already running jobs. Let's refcount the MMU context object
so it's lifetime is no longer bound to the FD lifetime and running jobs
can finish properly without generating spurious page faults.

drm/panfrost: perfcnt: fix ref count leak in panfrost_perfcnt_enable_locked
in panfrost_perfcnt_enable_locked, pm_runtime_get_sync is called which
increments the counter even in case of failure, leading to incorrect
ref count. In case of failure, decrement the ref count before returning.

drm/panfrost: add regulators to devfreq
Some OPP tables specify voltage for each frequency. Devfreq can
handle these regulators but they should be get only 1 time to avoid
issue and know who is in charge.
If OPP table is probe don't init regulator.

drm/panfrost: dynamically alloc regulators
We will later introduce regulators managed by OPP.
Only alloc regulators when it's needed. This also help use
to release the regulators only when they are allocated.

drm/panfrost: move devfreq_init()/fini() in device
Later we will introduce devfreq probing regulator if they
are present. As regulator should be probe only one time we
need to get this logic in the device_init().
panfrost_device is already taking care of devfreq_resume()
and devfreq_suspend(), so it's not totally illogic to move
the devfreq_init() and devfreq_fini() here.

drm/panfrost: properly handle error in probe
Introduce a boolean to know if opp table has been added.
With this, we can call panfrost_devfreq_fini() in case of error
and release what has been initialised.

This use devfreq variable that will be lock with spinlock in future
patches. We should either introduce a function to access this one
but as devfreq is optional let's just remove it.

Bifrost devices do support the flush reduction feature, so on first job

If the GPU is powered off, the feature doesn't bring any benefit, so
don't try to read.
