drm/i915/gtt: Allocate va range only if vma is not bound
When we have bound vma into an address space, the layout
of page table structures is immutable. So we can be absolutely
certain that if vma is already bound, there is no need to
(re)allocate a virtual address range for it.
v2: - add sanity checks and remove superfluous GLOBAL_BIND set
- we might do update for an unbound vma (Chris)

Parts of the DVO scaler logic have been revealed by reverse

patch (and the whole ns2501 DVO code) is currently only good for
the 1024x768 panel of the S6010, and may hopefully work on other

drm/i915: Fix up the vma aliasing ppgtt binding
Currently we have the problem that the decision whether ptes need to
be (re)written is splattered all over the codebase. Move all that into
i915_vma_bind. This needs a few changes:
- Just reuse the PIN_* flags for i915_vma_bind and do the conversion
to vma->bound in there to avoid duplicating the conversion code all
over.
- We need to make binding for EXECBUF (i.e. pick aliasing ppgtt if
around) explicit, add PIN_USER for that.
- Two callers want to update ptes, give them a PIN_UPDATE for that.
Of course we still want to avoid double-binding, but that should be
taken care of:
- A ppgtt vma will only ever see PIN_USER, so no issue with
double-binding.
- A ggtt vma with aliasing ppgtt needs both types of binding, and we
track that properly now.
- A ggtt vma without aliasing ppgtt could be bound twice. In the
lower-level ->bind_vma functions hence unconditionally set
GLOBAL_BIND when writing the ggtt ptes.
There's still a bit room for cleanup, but that's for follow-up
patches.
v2: Fixup fumbles.
v3: s/PIN_EXECBUF/PIN_USER/ for clearer meaning, suggested by Chris.

On Haswell and Broadwell with link in standby when exit event happens

The known W/A for this case involve the of single_frame update

increase performance by around 15% - though in practice improvements
will be marginal and rarely noticeable.

drm/i915: skylake scaler structure definitions
skylake scaler structure definitions. scalers live in crtc_state as
they are pipe resources. They can be used either as plane scaler or
panel fitter.
scaler assigned to either plane (for plane scaling) or crtc (for panel
fitting) is saved in scaler_id in plane_state or crtc_state respectively.
scaler_id is used instead of scaler pointer in plane or crtc state
to avoid updating scaler pointer everytime a new crtc_state is created.
v2:
-made single copy of min/max values for scalers (Matt)
v3:
-updated commentary for scaler_id (me)
v4:
-converted src/dst ranges to #defines, dropped ratios (Matt)

drm/i915: Allocate connector state together with the connectors
Connector states were being allocated in intel_setup_outputs() in loop
over all connectors. That meant hot-added connectors would have a NULL
state. Since the change to use a struct drm_atomic_state for the legacy
modeset, connector states are necessary for the i915 driver to function
properly, so that would lead to oopses.
v2: Fix test for intel_connector_init() success in lvds and sdvo (PRTS)
