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.

drm/radeon: Partial update to Linux 3.12

This brings new radeon features (mostly code refactoring):
DMA functions seperated from asics code;
UVD block separation;
Improvements to DPMS (by default disabled);
Better audio handling.

Notes:
drm/ttm layer is put into transitional state pending memory functions rewrite.
Currently VRAM handling capabilities are limited,
still enough for light gaming and watching videos.
X acceleration on radeon SI cards requires updated xorg+mesa(glamour support).

drm/i915: Update to Linux 3.16

* Much improved support for Broadwell GPUs. Acceleration should now be fully
operational and the giant L4 eDRAM cache is now enabled when present.

* Baytrail/Valleyview support improvements

* prelimary support for Cherryview (14nm Atom SOCs)

* Various fixes and performance improvements on most other GPU generations

* Improved runtime power management

* 5.4GHz DisplayPort support

* Large cursor support (up to 256x256 pixels), useful for high-dpi displays.

* Mapping of user pages into video memory (userptr)
This allows zero-copy downloads and efficient readback to/from the GPU,
allowing faster rendering of client-side software rasterisers, mitigation
of stalls due to read back and faster pipelining of texture data (such as
pixel buffer objects in GL or data blobs in CL). Mixed CPU/GPU operations
become more efficient in general.
