drm/i915: Kill legeacy AGP for gen3 kms
and with ums now gone to there's really no users any more.
Note that device_is_agp is only called when DRIVER_USE_AGP is set and
since we've unconditionally cleared that since a while there are
really no users left for i915_driver_device_is_agp.

This is required for DPMS to work correctly, during a modeset
the DPMS property should be turned off, unless the state is
crtc is made active in which case it should be set to DPMS on.
Changes since v1:
- Set DPMS to off when a connector is removed from a crtc too.
- Update the legacy dpms property too.
- Add an exception for the legacy dpms paths, it updates its own state.
Changes since v2:
- Do not preserve dpms property.

This is required to properly handle failing dpms calls.
When making a wait in i915 interruptible, I've noticed
that the dpms sequence could fail with -ERESTARTSYS because
it was waiting interruptibly for flips. So from now on

Chris rightfully suggested that documenting fences without documenting
the BO tiling tracking doesn't make much sense, so fix that.
The important bit to stress here (since it lead to some confusion) is
the GEM doesn't really care about tiling. Except for a few select cases
where the kernel needs to manage something that userspace can't take
care of: Namely the limited number of fences and fixing up swizzling,
although we still fail at the later.
v2: Move the low-level tiling/swizzling functions and kerneldoc to
i915_gem_fence.c and leave only the userspace interface here.

While auditing various users of the connector/encoder lists I realized
that the atomic code is a very prolific user of them. And it only ever
grabs the mode_config->connection_mutex, but not the
mode_config->mutex like all the other code walking encoder/connector
lists.
The problem is that we can't grab the mode_config.mutex late in atomic
code since that would lead to locking inversions. And we don't want to
grab it unconditionally like the legacy set_config modeset path since
that would render all the fine-grained locking moot.
Instead just grab more locks in the dp mst hotplug code. Note that
drm_connector_init (which is the one adding the connector to these
lists) already uses drm_modeset_lock_all.
The other reason for grabbing all locks is that the dpms off in the
unplug function amounts to a modeset, so better to take all required
locks for that.

Since the hardware sometimes mysteriously totally flummoxes the 64bit
read of a 64bit register when read using a single instruction, split the
read into two instructions. Since the read here is of automatically
incrementing timestamp counters, we also have to be very careful in
order to make sure that it does not increment between the two
instructions.
However, since userspace tried to workaround this issue and so enshrined
this ABI for a broken hardware read and in the process neglected that
the read only fails in some environments, we have to introduce a new
uABI flag for userspace to request the 2x32 bit accurate read of the
timestamp.
v2: Fix alignment check and include details of the workaround for
userspace.

The Golden batch carries 3D state at the beginning so that HW starts with
a known state. It is carried as a binary blob which is auto-generated from
source. The idea was it would be easier to maintain and keep the complexity
out of the kernel which makes sense as we don't really touch it. However if
you really need to update it then you need to update generator source and
keep the binary blob in sync with it.
There is a need to patch this in bxt to send one additional command to enable
a feature. A solution was to patch the binary data with some additional
data structures (included as part of auto-generator source) but it was
unnecessarily complicated.
Chris suggested the idea of having a secondary batch and execute two batch
buffers. It has clear advantages as we needn't touch the base golden batch,
can customize secondary/auxiliary batch depending on Gen and can be carried
in the driver with no dependencies.
This patch adds support for this auxiliary batch which is inserted at the
end of golden batch and is completely independent from it. Thanks to Mika
for the preliminary review.
v2: Strictly conform to the batch size requirements to cover Gen2 and

Fastboot should only downgrade a modeset if we have a match, not be
used to upgrade to a full modeset. Otherwise we can only use it in a
very restricted way: Initial modeset when the request mode is the
preferred one of the panel and there's still a pfit active. And that
only works because our mode_from_pipe_config fills in the wrong mode
(it takes the adjusted mode, not the requested one).
But we want fast modesets everywhere even after boot-up (especially
for testing, but not only there). Hence we need to be able to make any
modeset a fast one, which means we need to invert the logic and
optionally downgrade a modeset.
Note that this needs ->connector_changed split out from ->mode_changed
otherwise it's not going to work (because we might loose a modeset
because connectors changed but otherwise the config matches). As soon
as that's merged we can drop the i915.fastboot check from this code.
Also make sure that we don't accidentally clear any_ms and that we add
the planes for any kind of modeset.
Finally rename fastboot to fastset (yeah it's a silly name) since this
really isn't about booting all that much.

Simplify this by only using mode.private_flags and stop using the
INHERITED_MODE quirk. Also for clarity add an explicit #define for
that driver priavete mode flag.
By using crtc_state->mode_changed we can also remove the recalc local
