On Tegra234, engines that are programmed through Host1x channels can
be attached to either the NISO0 or NISO1 SMMU. Because of that, when
selecting a context device to use with an engine, we need to select
one that is also attached to the same SMMU.
Add a parameter to host1x_memory_context_alloc to specify which device
we are allocating a context for, and use it to pick an appropriate
context device.

Engine busyness samples around a 10ms period is failing with busyness
ranging approx. from 87% to 115% as shown below. The expected range is
+/- 5% of the sample period. Fail 10% of the time.
rcs0: reported 11716042ns [91%] busyness while spinning [for 12805719ns]
When determining busyness of active engine, the GuC based engine
busyness implementation relies on a 64 bit timestamp register read. The
latency incurred by this register read causes the failure.
On DG1, when the test fails, the observed latencies range from 900us -
1.5ms.
Optimizing the 2x32 read by acquiring the lock and forcewake prior to
all reg reads reduces the rate of failure to around 2%, but does not
eliminate it.
In order to make the selftest more robust and always account for such
latencies, increase the sample period to 100 ms. This eliminates the
issue as seen in a 1000 runs.

- Add error to commit msg

bigjoiner_pipes() doesn't consider that:
- RKL only has three pipes
- some pipes may be fused off
This means that intel_atomic_check_bigjoiner() won't reject
all configurations that would need a non-existent pipe.
Instead we just keep on rolling witout actually having
reserved the slave pipe we need.
It's possible that we don't outright explode anywhere due to
this since eg. for_each_intel_crtc_in_pipe_mask() will only
walk the crtcs we've registered even though the passed in
pipe_mask asks for more of them. But clearly the thing won't
do what is expected of it when the required pipes are not
present.
Fix the problem by consulting the device info pipe_mask already
in bigjoiner_pipes().

The GT MCR code currently relies on uncore->lock to avoid race
conditions on the steering control register during MCR operations. The
*_fw() versions of MCR operations expect the caller to already hold
uncore->lock, while the non-fw variants manage the lock internally.
However the sole callsite of intel_gt_mcr_wait_for_reg_fw() does not
currently obtain the forcewake lock, allowing a potential race condition
(and triggering an assertion on lockdep builds). Furthermore, since
'wait for register value' requests may not return immediately, it is
undesirable to hold a fundamental lock like uncore->lock for the entire
wait and block all other MMIO for the duration; rather the lock is only
needed around the MCR read operations and can be released during the
delays.
Convert intel_gt_mcr_wait_for_reg_fw() to a non-fw variant that will
manage uncore->lock internally. This does have the side effect of
causing an unnecessary lookup in the forcewake table on each read
operation, but since the caller is still holding the relevant forcewake
domain, this will ultimately just incremenent the reference count and
won't actually cause any additional MMIO traffic.
In the future we plan to switch to a dedicated MCR lock to protect the
steering critical section rather than using the overloaded and
high-traffic uncore->lock; on MTL and beyond the new lock can be
implemented on top of the hardware-provided synchonization mechanism for
steering.

One-element arrays are deprecated, and we are replacing them with
flexible array members instead. So, replace one-element array with
flexible-array member in struct GOP_VBIOS_CONTENT and refactor the
rest of the code accordingly.
Important to mention is that doing a build before/after this patch
results in no functional binary output differences.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

- If we fail validation, we should retain the phantom
stream/planes
- Full updates assume that phantom pipes will be fully
removed, but if validation fails we keep the phantom
pipes
- Therefore we have to retain the plane/stream if validation
fails (since the refcount is decremented before validation,
and the expectation is that it's fully freed when the old
dc_state is released)
