Now the EDID property will be updated when the corresponding EDID can be
obtained from the external display device. But after the external device
is plugged-out, the EDID property is not updated. In such case we still
get the corresponding EDID property although it is already detected as
disconnected.

We tried to implement interruptible waiting with timeout (it was broken
anyway) which was not a good idea as explained by Andrew. It's possible
to avoid using additional variable but actually it inroduces using more
complex in-kernel tools. So simply add one variable for condition.

R6xx+ cards need to use the 3D engine to blit data which requires
quite a bit of hw state setup.  Rather than pull the whole 3D driver
(which normally generates the 3D state) into the DRM, we opt to use
statically generated state tables.  The regsiter state and shaders
were hand generated to support blitting functionality.  See the 3D
driver or documentation for descriptions of the registers and
shader instructions.

VRAM->system is a synchronous operation: it involves scheduling a
VRAM->TT DMA transfer and stalling the CPU until it's finished so that
we can unbind the new memory from the translation tables. VRAM->TT can
always be performed asynchronously, even if TT is already full and we
have to move something out of it.

Additionally, allowing VRAM->system behaves badly under heavy memory
pressure because once we run out of TT, stuff starts to be moved back
and forth between VRAM and system, and the TT contents are hardly
renewed.

The connector table index in the DCB entry for each output type is an

with what was previously called "index" in the connector table entries
themselves.
