In order to reduce the DC5->DC2 restore time, wakelocks have been
introduced in DMC so the driver can tell it when registers and other
memory areas are going to be accessed and keep their respective blocks
awake.
Implement this in the driver by adding the concept of DMC wakelocks.
When the driver needs to access memory which lies inside pre-defined
ranges, it will tell DMC to set the wakelock, access the memory, then
wait for a while and clear the wakelock.
The wakelock state is protected in the driver with spinlocks to
prevent concurrency issues.

("drm/amdgpu: Remove TTM resource->start visible VRAM condition v2")
But this one was missed because it's working on the resource and not the

this will now trigger invalid mapping errors.

Handle only bigjoiner masters in skl_commit_modeset_enables/disables,
slave crtcs should be handled by master hooks. Same for encoders.
That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave.
v2: - Moved skl_pfit_enable, intel_dsc_enable, intel_crtc_vblank_on to intel_enable_ddi,
so that it is now finally symmetrical with the disable case, because currently
for some weird reason we are calling those from skl_commit_modeset_enables, while
for the disable case those are called from the ddi disable hooks.
v3: - Create intel_ddi_enable_hdmi_or_sst symmetrical to
intel_ddi_post_disable_hdmi_or_sst and move it also under non-mst check.
v4: - Fix intel_enable_ddi sequence
- Call intel_crtc_update_active_timings for slave pipes as well
[v5: vsyrjala: Use the name 'pipe_crtc' for the per-pipe crtc pointer
Use consistent style and naming
Protect macro arguments properly
Drop superfluous changes to the modeset sequence,
this now follows the old non-joiner sequence 100%
apart from just looping in places]

Extract the "not-MST" stuff from intel_ddi_post_disable() so that
the whole thing isn't so cluttered.
The bigjoiner slave handling was outside of the !MST check,
but it really should have been inside it as its the counterpart
to the master handling inside the check. So we pull that
in as well. There is no functional change here as we don't
currently support bigjoiner+MST anyway.
v2: Rebase
v3: Actually extract the slave code as claimed in
the commit message (presumably a rebase fail in v2)

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1] [2].
In this case, the memory allocated to store RADEONFB_CONN_LIMIT pointers
to "drm_connector" structures can be avoided. This is because this
memory area is never accessed.
Also, in the kzalloc function, it is preferred to use sizeof(*pointer)
instead of sizeof(type) due to the type of the variable can change and
one needs not change the former (unlike the latter).
At the same time take advantage to remove the "#if 0" block, the code
where the removed memory area was accessed, and the RADEONFB_CONN_LIMIT
constant due to now is never used.
