[why]
This Unit correction exposes a Replay corruption.

This reverts commit:
commit dbd29029 ("drm/amd/display: Correct unit conversion for vstartup")

Roll back unit conversion until Replay can fix their corruption.

[Why&How]
DMUB subsystem was continuing to use compile time offset calculation for
register access. Switch this to runtime calculation to stay consistent
with rest of DC code.

To enable this, an additional interface init_reg_offsets() are added to
DMUB's hw_funcs struct. Asics with runtime register offset calculation
enabled shall populate this hook with a fn pointer that will invoke the
necessary macros to calculate the offset.

[WHY & HOW]
PQ has a fixed range of 0-10,000 nits.
Using 1=80 nits normalization, PQ should map to 1.0 for X=125.0
HW LUT used for interpolation does not have X=125 so it's interpolated.
However, we cap Y to 1 for all X>=125.

The closest larger HW point is 128.
What we want is Y(128) such that interpolation through 125 gives 1.0.
Such value is ~1.00256.
Another change is to hardcode PQ table, we pretty much always have 1=80
normalization so the table can be static.

[WHY & HOW]
HW LUTs changed slightly in DCN3: 256 base+slope pairs were replaced by
257 bases. Code was still calculating all 256 base+slope and then
creating 257th pt as last base + last slope.
This was done in wrong format, and then "fixed" it by making the last
two points the same thus making the last slope=0.
However, this also created some precision problems near the end that
are not visible but they do show up with capture cards.

Solution is to calculate 257 and remove deltas since we no longer have
those HW registers.

Currently, NO_PREFETCH is passed implicitly through
drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len.

Since this is a direct representation of how the HW is programmed it
isn't really future proof for a uAPI. Hence, fix this up for the new
uAPI and split up the va_len field of struct drm_nouveau_exec_push,
such that we keep 32bit for va_len and 32bit for flags.

For drm_nouveau_gem_pushbuf_push::length at least provide
NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift.

While at it, fix up nv50_dma_push() as well, such that the caller
doesn't need to encode the NO_PREFETCH flag into the length parameter.

If a sched job depends on a dma-fence from a job from the same GPU
scheduler instance, but a different scheduler entity, the GPU scheduler
does only wait for the particular job to be scheduled, rather than for
the job to fully complete. This is due to the GPU scheduler assuming
that there is a scheduler instance per ring. However, the current
implementation, in order to avoid arbitrary amounts of kthreads, has a
single scheduler instance while scheduler entities represent rings.

As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all
out-fences in order to force the scheduler to wait for full job
completion for dependent jobs from different entities and same scheduler
instance.

There is some work in progress [1] to address the issues of firmware
schedulers; once it is in-tree the scheduler topology in Nouveau should
be re-worked accordingly.

After the commit in the Fixes: line below, HPD polling stopped working
on i915, since after that change calling drm_kms_helper_poll_enable()
doesn't restart drm_mode_config::output_poll_work if the work was
stopped (no connectors needing polling) and enabling polling for a
connector (during runtime suspend or detecting an HPD IRQ storm).

After the above change calling drm_kms_helper_poll_enable() is a nop
after it's been called already and polling for some connectors was
disabled/re-enabled.

Fix this by calling drm_kms_helper_poll_reschedule() added in the
previous patch instead, which reschedules the work whenever expected.
