drm cleanup 12/x: Layout fixes to match upstream in drmP.h

Mainly to reduce differences for upcomming further cleanup.

Strictly no functional change.

drm cleanup 11/x: Remove some unused callbacks from drm_driver.

drm cleanup 10/x: Move DRM_WAIT_ON and DRM_CURRENTPID macros.

DRM_CURRENTPID macro will no longer be used after v4.4

drm cleanup 06/x: Remove KIB_NOTYET macro.

Not used even at FreeBSD.

While there, remove few other from initial port.

drm cleanup 03/x: Move all includes in drmP.h to the top.

drm cleanup 03/x: Move all includes in drmP.h to the top.

Hide struct videomode under CONFIG_VIDEOMODE_HELPERS option.
There is no need for it in DragonFly.

While there, resort include order to match one at Linux v4.3

No functional change intended.

drm cleanup 01/x: Move legacy buffer structs to drm_leagcy.h

As was done in Linux v3.18 commit:

drm/i915: Update to Linux 4.3

* Generic stability improvements

* Stability fixes and support improvements for various GPU families, including

drm/i915: Update to Linux 4.3

* Generic stability improvements

* Stability fixes and support improvements for various GPU families, including
Broxton, Valleyview, Cherryview, Broadwell and Skylake

* Skylake support is no longer considered experimental

* HDMI now uses 12 bits per color component if the screen supports it.

* Power saving features improvements: many fixes have been made to the
PSR (panel self refresh) and FBC (framebuffer compression) code.
These features are not yet enabled by default though.

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: Store PCI device information in a struct pci_dev

Reducing differences with Linux

drm: Always enable MSI interrupts

The Linux drm code doesn't contain any blacklist for hardware with
broken MSI support; there is no reason for MSI interrupts to not work
with DragonFly either.

drm - Fix panic on DRM_IOCTL_WAIT_VBLANK

* DRM_IOCTL_WAIT_VBLANK -> drm_wait_vblank() -> DRM_WAIT_ON() -> panic

DRM_WAIT_ON() assumed that the device was locked and tried to unlock
and relock it around the tsleep. However, the ioctl paths that use
this function do not lock the device.

* Remove the unlock/relock sequence.

* Tested on haswell using ioctl call w/vblank.request.type =
_DRM_VBLANK_RELATIVE and vblank.request.sequence = 10. Crash reproduced
before fix, does not occur after fix.

drm/i915: Upgrade to Linux 4.0

* Basic Skylake support

* Panel Self-Refresh (PSR) now supported on Valleyview and Cherryview

* Preparations for atomic display updates

* Performance improvements on various GPU families, including Cherryview,
Broadwell and Haswell

* GPU frequencies are now kept at a minimum of 450MHz when possible
on Haswell and Broadwell, ensuring a minimum experience level for
various types of workloads

* Improved reset support for gen3/4 GPUs, which should fix some OpenGL
crashes on Core 2 and pre-2012 Atom machines

* Better sound/graphics driver synchronization for audio over hdmi support

* As usual, small bugfixes and stability improvements here and there
