DSI and WB interfaces need a more complex pipeline configuration
than the current mdp5_ctl_set_intf().
For example, memory output connections need to be selected for
WB. Interface mode (Video vs. Command modes) also need to be
configured for DSI.
This change takes care of configuring the whole pipeline as far
as operation mode goes. DSI and WB interfaces will be added
later.

MDP5 hardware has some limitation and requires to avoid flushing

This change removes all FLUSH operations (except for HW cursor)
beside the one coming from a CRTC's ->atomic_flush().
This avoid this type of behavior (eg: CRTC + 1 plane overlay):
[drm:mdp5_crtc_vblank_irq] vblank
[drm:mdp5_ctl_commit] flush (20048) CTL + LM0 + RGB0
[drm:mdp5_ctl_commit] flush (20040) CTL + LM0
[drm:mdp5_crtc_vblank_irq] blank
[drm:mdp5_ctl_commit] flush (20049) CTL + LM0 + RGB0 + VIG0
[drm:mdp5_crtc_vblank_irq] blank
and replaces it by:
[drm:mdp5_crtc_vblank_irq] vblank
[drm:mdp5_ctl_commit] flush (20048) CTL + LM0 + RGB0
[drm:mdp5_crtc_vblank_irq] blank
[drm:mdp5_ctl_commit] flush (20049) CTL + LM0 + RGB0 + VIG0

Users of the atomic state assume that if the pointer to a crtc, plane or
connector is not NULL in the respective object vector, than the state
for that object in *_states vector also won't be NULL. That assumption
was broken by drm_atomic_state_clear(), which would clear the state
pointer but leave the pointer to the object still set.
This fixes a NULL pointer dereference in i915 caused by the use of
drm_atomic_state_clear().

To allow for views where the view type is not defined by the view type only,
like it is in stereo or rotated 90 degree view, change the semantic to require
the whole view structure for comparison when we match a GGTT view.
This allows including parameters like offset to be included in the view which
is useful for eg. partial views.
v3:
- Rely on ggtt_view type being 0 for non-GGTT vma's, which equals to
I915_GGTT_VIEW_NORMAL. (Daniel Vetter)
- Do not use potentially slower comparison when we only want to know if
something is or is not a normal view.
- Rebase on top of rotated view patches. Add rotated view singleton.
- If one view is missing in comparison they're equal only if both are missing.

This patch continues on the idea from "Track GEN6 page table usage".
From here on, in the steady state, PDEs are all pointing to the scratch
page table (as recommended in the spec). When an object is allocated in
the VA range, the code will determine if we need to allocate a page for
the page table. Similarly when the object is destroyed, we will remove,
and free the page table pointing the PDE back to the scratch page.
Following patches will work to unify the code a bit as we bring in GEN8
support. GEN6 and GEN8 are different enough that I had a hard time to
get to this point with as much common code as I do.
The aliasing PPGTT must pre-allocate all of the page tables. There are a
few reasons for this. Two trivial ones: aliasing ppgtt goes through the
ggtt paths, so it's hard to maintain, we currently do not restore the
default context (assuming the previous force reload is indeed
necessary). Most importantly though, the only way (it seems from
empirical evidence) to invalidate the CS TLBs on non-render ring is to
either use ring sync (which requires actually stopping the rings in
order to synchronize when the sync completes vs. where you are in
execution), or to reload DCLV. Since without full PPGTT we do not ever
reload the DCLV register, there is no good way to achieve this. The
simplest solution is just to not support dynamic page table
creation/destruction in the aliasing PPGTT.
We could always reload DCLV, but this seems like quite a bit of excess
overhead only to save at most 2MB-4k of memory for the aliasing PPGTT
page tables.
v2: Make the page table bitmap declared inside the function (Chris)
Simplify the way scratching address space works.
Move the alloc/teardown tracepoints up a level in the call stack so that
both all implementations get the trace.
v3: Updated trace event to spit out a name
v4: Aliasing ppgtt is now initialized differently (in setup global gtt)
v5: Rebase to latest code. Also removed unnecessary aliasing ppgtt check
for trace, as it is no longer possible after the PPGTT cleanup patch series
of a couple of months ago (Daniel).
v6: Implement changes from code review (Daniel):
- allocate/teardown_va_range calls added.
- Add a scratch page allocation helper (only need the address).
- Move trace events to a new patch.
- Use updated mark_tlbs_dirty.
- Moved pt preallocation for aliasing ppgtt into gen6_ppgtt_init.
v7: teardown_va_range removed (Daniel).
In init, gen6_ppgtt_clear_range call is only needed for aliasing ppgtt.
v8: Rebase after s/page_tables/page_table/.
v9: Remove unnecessary scratch flag in page_table struct, future patches
can just compare against ppgtt->scratch_pt, and alloc_pt_scratch becomes
redundant. Initialize scratch_pt and pt. (Mika)
v10: Clean up aliasing ppgtt init error path and prevent leaking the
ppgtt obj when init fails. (Mika)
