This enabled interrupt driven hpd support for all
radeon chips.  Assuming the hpd pin is wired up
correctly, the driver will generate uevents on
digital monitor connect and disconnect and retrain
DP monitors automatically.

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

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.
