drm/omap: work-around for omap3 display enable

Seems that on omap3 enabling a crtc without any planes causes a sync
lost flood. This only happens on the first enable, and after that it
works. This looks like an HW issue and it's unclear why this is
happening or how to fix it.

This started happening after 897145d0c7010b4e07fa9bc674b1dfb9a2c6fff9
("drm/omapdrm: Move commit_modeset_enables() before commit_planes()")

and plane set only after that. This WA should be fine on all DSS
versions, but apparently OMAP3 DSS is an exception.

drm/i915/bxt: use NULL for GPIO connection ID

The commit 213e08ad60ba
("drm/i915/bxt: add bxt dsi gpio element support")
enables GPIO support for Broxton based platforms.

While using that API we might get into troubles in the future, because
we can't rely on label name in the driver since vendor firmware might
provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in
which case the request will fail).

To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
   acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.

The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, has been made stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, is
making request fail.

drm/i915: Mark the GT as busy before idling the previous request

In a synchronous setup, we may retire the last request before we
complete allocating the next request. As the last request is retired, we
queue a timer to mark the device as idle, and promptly have to execute
ad cancel that timer once we complete allocating the request and need to
keep the device awake. If we rearrange the mark_busy() to occur before
we retire the previous request, we can skip this ping-pong.

v2: Joonas pointed out that unreserve_seqno() was now doing more than
doing seqno handling and should be renamed to reflect its wider purpose.
That also highlighted the new asymmetry with reserve_seqno(), so fixup
that and rename both to [un]reserve_engine().

drm/i915: Replace execbuf vma ht with an idr

This was the competing idea long ago, but it was only with the rewrite
of the idr as an radixtree and using the radixtree directly ourselves,
along with the realisation that we can store the vma directly in the
radixtree and only need a list for the reverse mapping, that made the
patch performant enough to displace using a hashtable. Though the vma ht
is fast and doesn't require any extra allocation (as we can embed the node
inside the vma), it does require a thread for resizing and serialization
and will have the occasional slow lookup. That is hairy enough to
investigate alternatives and favour them if equivalent in peak performance.
One advantage of allocating an indirection entry is that we can support a
single shared bo between many clients, something that was done on a
first-come first-serve basis for shared GGTT vma previously. To offset
the extra allocations, we create yet another kmem_cache for them.

gen6_reset_engines() was to keep the bookkeeping intact because the

In reset we try to restore the forcewake state to
pre reset state, using forcewake_count. The reset
doesn't seem to clear the forcewake bits so we
get warn on forcewake ack register not clearing.

The new danger with using intel_uncore_forcewake_reset() with per-engine
resets is that the driver and hw are still in an active state as we
perform the reset. We may be using the forcewake to read protected
registers elsewhere and those results may be clobbered by the concurrent
