This moves the radeon DP link training call to happen when we
dpms on the encoder not when we set the mode.

This fix reorganises the initial DP link training slightly, and
actually makes DP work under kms here.

Both radeon and nouveau can re-use this code so move it up a level
so they can. However the hw interfaces for aux ch are different
enough that the code to translate from mode, address, bytes
to actual hw interfaces isn't generic, so move that code into the
Intel driver.

This is intended to be used by ttm-aware drivers to

2) Optionally block clients to the current master when
there is thrashing due to GPU memory shortage.

Again we try to put VRAM at 0, and it didn't work on this chipset,
reports of corrupt RAM appeared on irc and bugzilla.

Fix the vram location according to what the BIOS setup, I'm not 100%
sure we don't need the same thing on rs690/rs780/rs880, we probably
should do it there just in case as its what the DDX does.

This commit adds a ioctl and property to allow userspace
to notify the kernel that a framebuffer has changed. Instead
of snooping the command stream this allows finer grained
tracking of which areas have changed.

The primary user for this functionality is virtual hardware
like the vmware svga device, but also Xen hardware likes to
be notify. There is also real hardware like DisplayLink and
DisplayPort that might take advantage of this ioctl.
