When introducing asynchronous unbinding, the vma itself may no longer
be alive when the actual binding or unbinding takes place.
Update the gtt i915_vma_ops accordingly to take a struct i915_vma_resource
instead of a struct i915_vma for the bind_vma() and unbind_vma() ops.
Similarly change the insert_entries() op for struct i915_address_space.
Replace a couple of i915_vma_snapshot members with their newly introduced
i915_vma_resource counterparts, since they have the same lifetime.
Also make sure to avoid changing the struct i915_vma_flags (in particular
the bind flags) async. That should now only be done sync under the
vm mutex.
v2:
- Update the vma_res::bound_flags when binding to the aliased ggtt
v6:
- Remove I915_VMA_ALLOC_BIT (Matthew Auld)
- Change some members of struct i915_vma_resource from unsigned long to u64
(Matthew Auld)
v7:
- Fix vma resource size parameters to be u64 rather than unsigned long

Big delta, but boils down to moving set_pages to i915_vma.c, and removing
the special handling, all callers use the defaults anyway. We only remap
in ggtt, so default case will fall through.
Because we still don't require locking in i915_vma_unpin(), handle this by
using xchg in get_pages(), as it's locked with obj->mutex, and cmpxchg in
unpin, which only fails if we race a against a new pin.
Changes since v1:
- aliasing gtt sets ZERO_SIZE_PTR, not -ENODEV, remove special case
from __i915_vma_get_pages(). (Matt)
Changes since v2:
- Free correct old pages in __i915_vma_get_pages(). (Matt)
Remove race of clearing vma->pages accidentally from put,
free it but leave it set, as only get has the lock.

At least the Bay Trail LPSS PWM controller used with DSI panels on many
Bay Trail tablets seems to leave the PWM pin in whatever state it was
(high or low) ATM that the PWM gets disabled. Combined with some panels
not having a separate backlight-enable pin this leads to the backlight
sometimes staying on while it should not (when the pin was high during
PWM-disabling).
First calling intel_backlight_set_pwm_level() will ensure that the pin
is always low (or high for inverted brightness panels) since the passed
in duty-cycle is 0% (or 100%) when the PWM gets disabled fixing the
backlight sometimes staying on.
With the exception of ext_pwm_disable_backlight() all other
foo_disable_backlight() functions call intel_backlight_set_pwm_level()
already before disabling the backlight, so this change also aligns
ext_pwm_disable_backlight() with all the other disable() functions.

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.

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...

Add display/intel_display_trace.[ch] for defining display
tracepoints. The main goal is to reduce cross-includes between gem and
display. It would be possible split up tracing even further, but that
would lead to more boilerplate.
We end up having to include intel_crtc.h in a few places because it was
pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and
that's no longer the case.
There should be no changes to tracepoints.
