During check_crtc_state, scaler_id mispatch is being reported for HSW.

drm/i915: skylake panel fitting using shared scalers
This patch will make sure that we leave scaler_id as 0 for platforms
before skl and set for skl+ only. This way scaler_id check during
check_crtc_state will pass for both prior to skl and skl+ platforms.
v2:
-Leave scaler_id as 0 for gen < 9 (Daniel)

As we perform the mmio-flip without any locking and then try to acquire
the struct_mutex prior to dereferencing the request, it is possible for
userspace to queue a new pageflip before the worker can finish clearing
the old state - and then it will clear the new flip request. The result
is that the new flip could be completed before the GPU has finished
rendering.
The bugs stems from removing the seqno checking in

Synchronising to an object active on the same ring is a no-op, for the
benefit of execbuffer scheduler. However, for CS flips this means that
we can forgo checking whether the last write request of the object is
actually queued and more importantly whether the cache flush for the
write was emitted.

Replace the drivers own logic for computing mode_changed, active_changed
and planes_changed flags with the check_modeset() atomic helper. Since
that function needs to compare the crtc's new mode with the current,
this patch also moves the set up of crtc_state->mode earlier in the call
chain.
Note that for the call to check_plane() to work properly, we need to
check new plane state against new crtc state. But since we still use the
plane update helper, which doesn't have a full atomic state, we need to
hack around that in intel_plane_atomic_check().

Since the introduction of BIOS fb preservation, circa 3.17, we began
encountering a failure during boot when trying to use force-detect
before GEM was initialised. That bug is from

drm/i915: ensure the force pipe A quirk is actually followed
but investigation of the affected machine revealed that it was using a
PIPE-A quirk even though it was a 945GSE and the quirk is only supposed
to be used to workaround a hardware issue on 830/845. That quirk was
added for this HP Mini in

add pipe a force quirk for Dell mini
in order to workaround an issue with the BIOS behaving strangely during
lid-close. Since then we have a much larger hammer to thwart the BIOS
after opening the lid and the PIPE-A quirk is no longer required.

The checks for PLL enabled state on CPU ports are valid only on GMCH
platforms but atm we'd also call them on non-PCH-split/non-GMCH
platforms like BXT, triggering false warnings. Until the proper check is
implented for these platforms simply disable the check.
