drm/amdgpu: Port to DragonFly

* This commit does not build as it requires ttm changes from
the corresponding commit

Amdgpu driver changes:
* Builds with CONFIG_DRM_AMD_DC and CONFIG_DRM_AMD_DC_DCN1_0 defined
* Support for older GPUs (SI, CIK) is not implemented
* Several functions for display core module require msse and
mhard-float gcc flags to be set; and they require special
treatment from kernel by utilizing kernel_fpu_begin/kernel_fpu_end
functions
* It is required that tunable set amdgpu_hw_i2c=1 to work around
panic during module load
* Thunderbolt support is disabled
* Amdgpu trace infrastructure replaced by a stub

Drm changes:
* register_framebuffer is called at the later stage, after crtcs
were properly initialized
* drm_close implemented
* drm_connector_update_edid_property implemented
* Fix drm device stays locked in case of an error or module shutdown
* Imported drm gem framebuffer helper functions
* Fixed null pointer deref in the drm mmap ioctl
* Imported atomic64_inc and atomic_long_* functions from Linux
* Imported bitmap_complement function from Linux
* Imported kfifo struct from Linux
* Implemented dma fence array properly
* Imported rb_root_cached struct from Linux
* Implemented several dma fence functions

kernel - VM rework part 14 - Core pmap work, stabilize for X/drm

* Don't gratuitously change the vm_page flags in the drm code.

The vm_phys_fictitious_reg_range() code in drm_vm.c was clearing
PG_UNMANAGED. It was only luck that this worked before, but
because these are faked pages, PG_UNMANAGED must be set or the
system will implode trying to convert the physical address back
to a vm_page in certain routines.

The ttm code was setting PG_FICTITIOUS in order to prevent the
page from getting into the active or inactive queues (they had
a conditional test for PG_FICTITIOUS). But ttm never cleared
the bit before freeing the page. Remove the hack and instead
fix it in vm_page.c

* in vm_object_terminate(), allow the case where there are still
wired pages in a OBJT_MGTDEVICE object that has wound up on a
queue (don't complain about it). This situation arises because the
ttm code uses the contig malloc API which returns wired pages.

NOTE: vm_page_activate()/vm_page_deactivate() are allowed to mess
with wired pages. Wired pages are not anything 'special' to
the queues, which allows us to avoid messing with the queues
when pages are assigned to the buffer cache.

* Cleanup the API a bit

* Get rid of pmap_enter_quick()

* Remove unused procedures.

* Document that vm_page_protect() (and thus the related
pmap_page_protect()) must be called with a hard-busied page. This
ensures that the operation does not race a new pmap_enter() of the page.

kernel - refactor vm_page busy

* Move PG_BUSY, PG_WANTED, PG_SBUSY, and PG_SWAPINPROG out of m->flags.

* Add m->busy_count with PBUSY_LOCKED, PBUSY_WANTED, PBUSY_SWAPINPROG,
and PBUSY_MASK (for the soft-busy count).

* Add support for acquiring a soft-busy count without a hard-busy.
This requires that there not already be a hard-busy. The purpose
of this is to allow a vm_page to be 'locked' in a shared manner
via the soft-busy for situations where we only intend to read from
it.

drm/radeon: Update to Linux 3.17 (v2)

drm/radeon: Update to Linux 3.17 (v2)

Catch up with recent updates in i915kms driver.
While there perform some cleaning in drm and drm/ttm too.

This smallish(1.2MB) diff between Linux v3.12..v3.17 brings
few improvements for radeon cards support on DragonFly BSD.

Driver is VERY experimental even if FF 720p "Hey Mamma"
looks much more pleasing to the eyes on my Xeon box.

Me being Fortran developer(who wants to run OpenCL on BSDs too)
was literally throwing diffs at the fan to see what sticks on.
After cleaning up the mess a bit, these features seems to behave:
kms-syscons switching on R7 240 and 5770 JUNIPER;
current DPorts Xorg;
Xorg-next(1.17.2) + Mesa-next(glamor for radeonsi);
2D tiling now works out of the box on OLAND;
glxgears/cubemap/cuberender mesa demos;
firefox youtube videos(still some blinking on overlays);
mpv -vo vdpau --hwdec=vdpau bsd-0088.mp4 (--vo=opengl too);
UVD (decoding limited to 1080p frame streams);
fragging in OpenArena maxed-out(even ttys[0-8] to quickly check mail);
hdmi audio;
DPM (enabled by default);
gpu temperature monitoring through hw.sensors framework;
automatic firmware loading.

TODO:
update drm/ttm, any help would be really appreciated;
ww_mutex, yep still good old "homegrown" locks;
vma, newer shrinker api;
dma_buf/prime;
iic/i2c rework;
kldunload radeonkms;
better gart sizes support;
newer firmware format support;
fix failing ring sync test to ring-5(UVD);
check how driver supports X2 and IGP cards;
better OpenCL through Clover;
many more.

Thanks goes to:
ftigeot@efnet for opportunity and i915 work
YRabbit@efnet for extensive testing of hdmi A/V on TURKS
ivadasz@efnet for temperature sensors support
mneumann@efnet for testing on HAWAII

AMD for investing time and effort in opensource drivers
NetBSD and Linux gpu developers

Special thanks to:
everyone behind freebsd-ports-graphics/opencl (keep pushing the mngt!)

and that Sweet special girl out there.

the whole DRM subsystem and its drivers

Include sys/devfs.h in drm_vm.h and correct the use of
devfs_get_cdevpriv.

Reported-By: Sascha Wildner <saw@online.de>

drm relied on a custom hack to implement those functions, this hack
has now been removed, and the devfs based functions are used.

Keep things as close to Linux 3.5 as possible

than continuing to create new binutils branches for each new version.
