drm cleanup 15/x: Separate vblank DRM_DEBUG spam.

Attempt to make drm_debug=1 a bit more usable.
Rationale: vblank events are very noisy and makes live debugging
almost impossible. Also create problems with dmesg buffers etc.

By separating it into separate debug bit, hw.drm.debug=0x21f mode
is very useful to notice problems as they happen, spec during
reboot sequence when root fs is already unmounted and debugging
relies on dmesg contents getting into next boot to be read.

Bigger part of changes are in radeonkms side to prevent running
verbose diagnostics.

drm/radeon: Revert "drm/radeon: Partial sync with Linux 3.18"

This partially reverts commit bd519ccc430654ba519981ec2781920010d5bb19

Caused driver teardown problems.

drm/radeon: Partial sync with Linux 3.18

drm/radeon: Use pci_resource_start and pci_resource_len functions.

Replace calls to drm_get_resource_start and drm_get_resource_len
by pci_resource_start and pci_resource_len respectively.

Mostly bugfixes and audio refactoring, no new functionalities.

This update has been prepared by Rimvydas Jasinskas.

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).
