If we reduce the suspend function for intel_opregion to do the minimum

the ACPI bios that we are back. This avoid some nasty restrictions on

+INTEL_GEN_RANGE(e1, e2, FOREVER)
-INTEL_GEN(e1) <= e2

However I didn't like very much the remaining
INTEL_GEN(dev_priv) < n

INTEL_GEN(e1) < n
INTEL_GEN_RANGE(e1, 0, n - 1)

In order to ensure that our system suspend and resume callbacks are
called in the correct order wrt. those of the HDA driver add a device
link to the HDA driver during audio component binding time. With i915 as
the supplier and HDA as the consumer the PM framework will guarantee
the HDA->i915 suspend (and shutdown) and i915->HDA resume order.
Atm, the lack of this ordering is not a problem, since all the i915
suspend/resume steps that need to be ordered wrt. the HDA driver's
suspend/resume steps are separated out to the i915
suspend_late/resume_early hooks. That will change in a follow-up
patchset where we'll need this ordering guarantee for steps that are in
the i915 suspend/resume hooks (and which can't be moved to
suspend_late/resume_early for other reasons). So this patch is a
preparation for that follow-up patchset.
The change also allows us to move towards removing the i915
suspend_late/resume_early hooks alltogether.
Since we only need to ensure the ordering during suspend/resume and not
during driver probing create the link with DL_FLAG_STATELESS. Since the
probe time ordering has to be optional we use the component framework
for that.
Similarly for runtime PM we depend on the audio driver getting/putting
an i915 runtime PM reference whenever it needs it (along with the proper
i915 display power domain) via the audio component ops get_power /
put_power hooks. So we create the device link without
DL_FLAG_PM_RUNTIME.
v2: (Ville)
- Add a note to the commit message about not using the device link
runtime PM ordering.
- Handle the error return from device_link_add().

To make NV12 working on icl, we need to update 2 planes simultaneously.
I've chosen to do this in the CRTC step after plane validation is done,
so we know what planes are (in)visible. The linked Y plane will get
updated in intel_plane_update_planes_on_crtc(), by the call to
update_slave, which gets the master's plane_state as argument.
The link requires both planes for atomic_update to work,
so make sure skl_ddb_add_affected_planes() adds both states.

Propagate the timeout on transferring the fw back to the caller where it
may act upon it, usually by restarting the xfer before failing.
v2: Simplify the wait to only wait upon the guc signaling completion,
with an assertion that the fw xfer must have completed for it to be
ready!

Let's run through the entire plane check even when the plane
is invisible due to zero constant alpha. This makes for more
consistent behaviour since we check the src/dst coordinates,
stride etc. against the hardware limits.

The SKL+ NV12 src width alignment w/a is still living in an odd place.
Everything else was already relocated closer to the main plane check
function. Move this workaround as well.
As a bonus we avoid the funky rotated vs. not mess with the src
coordinates as this now gets checked before we rotate the coordinates.

The way our hardware is designed doesn't seem to let us use the
MI_RECORD_PERF_COUNT command without setting up a circular buffer.
In the case where the user didn't request OA reports to be available
through the i915 perf stream, we can set the OA buffer to the minimum
size to avoid consuming memory which won't be used by the driver.
v2: Simplify oa buffer size exponent selection (Chris)
Reuse vma size field (Lionel)
v3: Restrict size opening parameter to values supported by HW (Chris)
v4: Drop out of date comment (Matt)
Add debug message when buffer size is rejected (Matt)

We initialize the OA buffer everytime we enable the OA unit (first call in
gen[78]_oa_enable), so we don't need to initialize when preparing the metric
set.

commit e346a991f4 ("drm/i915/guc: drop negative doorbell alloc
selftest") removed the negative case from the selftest and left no
code between the goto from the positive case of the test and the label
itself, so we can get rid of it.
