Declare which FBC instances are present via a fbc_mask
in device info. For the moment there is just the one.
TODO: Need to figure out how to expose multiple FBC
instances in debugs. Just different file names, or move
the files under some subdirectory (per-crtc maybe), or
something else? This will need igt changes as well.
v2: Put the mask into device_info.display (Jani)
Put the magic pipe->fbc thing into skl_fbc_id_for_pipe() (Jani)

intel_cdclk.h only needs i915_drv.h for struct intel_cdclk_config. Move
the definition to intel_cdclk.h and turn the includes around to avoid
including i915_drv.h from other headers.
The intel cdclk state macros in intel_cdclk.h still reference struct
drm_i915_private, but as macros they don't strictly require the
definition until they are used.
v2: Expand on the commit message wrt cdclk state macros

Collect the dipslay related mask under the display sub-structure
in intel_device_info.
Note that there is a slight change in behaviour in that we zero
out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so
now we also zero out the other masks (although cpu_transocder_mask
should already be zero of pipe_mask is zero). abox_mask is
only used by the display core init when HAS_DISPLAY is true, so
the actual behaviour of the system shouldn't change despite the
zeroing of these masks.
There is a lot more display stuff directly in device info that
could be moved over. Maybe someone else will be inspired to do it...

There's no need to store all this stuff in intel_fbc_state_cache.
Just check it all against the plane/crtc states and store only
what we need. Probably more should get nuked still, but this
is a start.
So what we'll do is:
- each plane will check its own state and update its local
no_fbc_reason
- the per-plane no_fbc_reason (if any) then gets propagated
to the cache->no_fbc_reason while doing the actual update
- fbc->no_fbc_reason gets updated in the end with either
the value from the cache or directly from frontbuffer
tracking
It's still a bit messy, but should hopefuly get cleaned up
more in the future. At least now we can observe each plane's
reasons for rejecting FBC now more consistently, and we don't
have so mcuh redundant state store all over the place.
v2: store no_fbc_reason per-plane instead of per-pipe

With both integrated and discrete Intel GPUs in a system, the current
global check of intel_iommu_gfx_mapped, as done from intel_vtd_active()
may not be completely accurate.
In this patch we add i915 parameter to intel_vtd_active() in order to
prepare it for multiple GPUs and we also change the check away from Intel
specific intel_iommu_gfx_mapped (global exported by the Intel IOMMU
driver) to probing the presence of IOMMU on a specific device using
device_iommu_mapped().
This will return true both for IOMMU pass-through and address translation
modes which matches the current behaviour. If in the future we wanted to
distinguish between these two modes we could either use
iommu_get_domain_for_dev() and check for __IOMMU_DOMAIN_PAGING bit
indicating address translation, or ask for a new API to be exported from
the IOMMU core code.
v2:
* Check for dmar translation specifically, not just iommu domain. (Baolu)
v3:
* Go back to plain "any domain" check for now, rewrite commit message.
v4:
* Use device_iommu_mapped. (Robin, Baolu)

We currently have to special case vma->obj being NULL because
of gen6 ppgtt and mock_engine. Fix gen6 ppgtt, so we may soon
be able to remove a few checks. As the object only exists as
a fake object pointing to ggtt, we have no backing storage,
so no real object is created. It just has to look real enough.
Also kill pin_mutex, it's not compatible with ww locking,
and we can use the vm lock instead.

- Drop IS_SHRINKABLE and shorten overly long line
v3:
- Checkpatch fix for alignment
