drm/i915: Update to Linux 4.7.10

* Various bugfixes, including GPU-specific ones on Ironlake and more
recent hardware.
Runtime power management and atomic modesetting have been specially
improved.

* Fix Hardware hangs on Ironlake, Sandybridge, Ivybridge, Skylake and
Kabylake GPUs

* Fix various display flickering issues, including PSR, Broadwell and
Display-port specific ones

* Kabylake support is no longer considered experimental

* Color management has been added for Broadwell, Skylake, Kabylake as
well as Cherryview and Broxton GPUs. The intent is to obtain more
accurate color representation on various types of panel.

* Sync key portions of code with Linux 4.4

* Key drm functions using the DragonFly-specific iic(4) API
have been copied and renamed with an _iic suffix

* The drm/radeon driver no longer being actively developed, the
intent is to keep it functional with a frozen API

Thanks to Johannes Hofmann for figuring out we could live with
a dummy default bit_xfer() implementation

* Cherryview specific fixes

* Atomic modesetting conversion progress

* Improved validation of video modes. Some low-power chips can't
drive all DP screens and this is now detected by the driver.

* PSR and FBC improvements and bug fixes

* Workarounds for some specific HDMI monitors needing more time than
allowed by the spec to handle hot-plug events

* As usual, various fixes for little issues here and there

drm/i915: Update to Linux 4.2

* Work in progress atomic modesetting support

* Broadwell support improvements

* Skylake support improvements, including runtime power management.
Starting from Linux 4.2, a separate firmware blob is required to save
and restore the state of display engines in some low-power modes. These
low-power modes have been forcibly disabled in the DragonFly version of
this driver in order to keep it blob-free.

* Basic Broxton (BXT) support

* Various Displayport improvements including optimized link training,
increased robustness, and automated support for compliance testing

* Execlist overhead reduced

* Frequency boost tuning

* Plenty of bugfixes all around

drm/i915: Update to Linux 4.1

* Valleyview support has been vastly improved and is no longer considered
preliminary

* Skylake support improvements: runtime power management, turbo and sleep
states should now be fully operational.
Many workarounds have been added for Skylake specific issues

* Preliminary changes to prepare for Broxton (future Atom SOCs) support

* Distinguish hardware minimum and user minimum frequencies. Set the GPU
frequency to the hardware minimum on idle in order to reduce power usage

* DRRS (dynamic refresh rate switching) is now enabled where supported.
The idea is to reduce the refresh rate of the panel to save power when
nothing changes on the screen

* DP deadlock bugfixes and improved link rate computation. Intermediate
link rate support for eDP 1.4

* XenGT client-side support. This is paravirtualization to allow virtual
machines to tap into the render engines

* Plenty of internal work to prepare for atomic mode setting

* Lots of other smaller work all over such as added documentation, dead
UMS code removal, vblank interrupt cleanings, etc...

drm/i915: Update to Linux 3.14

Changes specific to the DragonFly driver:

* Most GEM code paths are now similar to Linux, leading to increased
stability and performance.
Making this change was greatly helped by studying the OpenBSD code.

* We were previously using legacy functions to set up page table entries and
this was starting to become a serious problem on particular platforms such
as gen4 or Broadwell. As of this commit, we now use the same chip-specific
virtual functions as Linux.

* RC6 and Frame Buffer Compression power savings enabled by default, depending
on the GPU family

Changes brought by the Linux 3.11 => 3.14 driver update:

* Various bug fixes on all GPU generations, especially stability improvements

* Power consumption improvements

* Many Valleyview/Baytrail support improvements

* The giant 128MB L4 cache is now enabled when present on Haswell

* Added support for Broadwell GPUs

* HDMI 4K support

* basic support for 3D/stereo displays on HDMI

* Hotplug IRQ storm detection and mitigation.

* Various bug fixes and performance improvements from GEN4 to
Haswell GPUs.
Less "Unclaimed register" messages should be visible on Haswell.

* Improved support for Valleyview / Baytrail GPUs.

* Better overclocking support from Sandy Bridge to Haswell.
Improved frequency scaling (turbo) on Haswell.

* Improved display detection and modesetting. It is now possible to
precompute possible desired display pipe configurations without
changing the hardware state.

accesses into the port array are therefore off-by-one and this
