This patch implements blit support for bo moves using
the 3D engine. It uses the same method as r6xx/r7xx:
- store the base state in an IB
- emit variable state and vertex buffers to do the blit
This allows the hw to move bos using the 3D engine and allows
full use of vram beyond the pci aperture size.

radeon_pm_in_vbl() didn't report in vblank status accurately. Make
it a wrapper around radeon_get_crtc_scanoutpos() which corrects for
biases, so it reports accurately.
radeon_pm_in_vbl() will only report in_vbl if all active crtc's
are currently inside vblank.

radeon_get_crtc_scanoutpos() returns the current horizontal
and vertical scanout position of a crtc. It also reports if
the display scanout is currently inside the vblank area.
hpos reports current horizontal pixel scanout position.
vpos reports the current scanned out line as a value >= 0
in active scanout. If the scanout is inside vblank area, it
reports a negative value, the number of scanlines until
end of vblank aka start of active scanout, e.g., -3 ==
"At most 3 scanlines until end of vblank".
This code is derived from radeon_pm_in_vbl(), tested on
R500 and R600.

This patch reworks spread spectrum handling to enable it
properly on lvds and DP/eDP links. It also fixes several
bugs in the old spread spectrum code.
- Use the ss recommended reference divider if available
when calculating the pll
- Use the proper ss command tables on pre-DCE3 asics
- Avoid reading past the end of the ss info tables
- Enable ss on evergreen asics (lvds, dp, tmds)
- Enable ss on DP/eDP links

The recent changes to the old algo (prefer high post div)
coupled with the range and precision limitations of using
fixed point with the new algo make the new algo less
useful. So drop the new algo. This should work as well
or better than the old new/old combinations and simplifies
the code a lot.

This allows for a more exact fitting on the physical
display. The new properties default to zero which corresponds to the
previous underscan border width[height] formula:
(display_width[display_width] >> 5) + 16.
Example to set a horizontal border width of 30 and a vertikal border
height of 22:
xrandr --output HDMI-0 --set underscan on --set "underscan hborder" 30 --set "underscan vborder" 22

On r6xx+ a newer fence mechanism was implemented to replace
the old wait_until plus scratch regs setup. A single EOP event
will flush the destination caches, write a fence value, and generate
an interrupt. This is the recommended fence mechanism on r6xx+ asics.
This requires my previous writeback patch.
v2: fix typo that enabled event fence checking on all asics
rather than just r6xx+.
v3: properly enable EOP interrupts

When writeback is enabled, the GPU shadows writes to certain
registers into a buffer in memory. The driver can then read
the values from the shadow rather than reading back from the
register across the bus. Writeback can be disabled by setting
the no_wb module param to 1.
On r6xx/r7xx/evergreen, the following registers are shadowed:
- CP scratch registers
- CP read pointer
- IH write pointer
On r1xx-rr5xx, the following registers are shadowed:
- CP scratch registers
- CP read pointer
v2:
- Combine wb patches for r6xx-evergreen and r1xx-r5xx
- Writeback is disabled on AGP boards since it tends to be
unreliable on AGP using the gart.
- Check radeon_wb_init return values properly.

This fixes a race pointed out by Dave Airlie where we don't take a buffer
object about to be destroyed off the LRU lists properly. It also fixes a rare
case where a buffer object could be destroyed in the middle of an
accelerated eviction.
The patch also adds a utility function that can be used to prematurely
release GPU memory space usage of an object waiting to be destroyed.
For example during eviction or swapout.
The above mentioned commit didn't queue the buffer on the delayed destroy
list under some rare circumstances. It also didn't completely honor the
remove_all parameter.
