Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next

So what we have for this cycle is a bit of spring cleaning with removal
of unused register logging code and getting rid of the license text in
favor of SPDX, a few smaller MMU handling improvements and a timeout
calculation change, fixing premature fence wait timeouts after 50 days
of uptime.

drm/etnaviv: replace license text with SPDX tags

This replaces the repetitive GPL-2.0 license text in code and header files
with the SPDX tags. Generated hardware headers aren't changed, as any changes
there need to be done in the upstream rnndb repository.

drm/etnaviv: bump HW job limit to 4

The current limit of 2 leads to some GPU idle times, as the usual
IRQ latency leads to up to 3 jobs getting signaled at once with some
standard workloads.

A larger HW job limit might lead to slightly worse QoS, but we accept
that to not sacrifice GPU throughput in the common case.

drm/etnaviv: replace hangcheck with scheduler timeout

This replaces the etnaviv internal hangcheck logic with the job timeout
handling provided by the DRM scheduler. This simplifies the driver further
and allows to replay jobs after a GPU reset, so only minimal state is lost.

This introduces a user-visible change in that we don't allow jobs to run
indefinitely as long as they make progress anymore, as this introduces
quality of service issues when multiple processes are using the GPU.
Userspace is now responsible to flush jobs in a way that the finish in a
reasonable time, where reasonable is currently defined as less than 500ms.

This hooks in the DRM GPU scheduler. No improvement yet, as all the
