None of the latest GPUs had this hooked up, this is necessary for

In the hotplug handler, just use the drm dpms functions.
If the monitor is plugged in, turn it on, if it's not,
turn it off. This also reduces power usage by turning
off the encoder and crtc when the monitor is unplugged.

In DP mode, the DP ref clock can come from PPLL, DCPLL, or ext clock,
depending on the asic. The crtc virtual pixel clock is derived from
the DP ref clock.
- DCE4: PPLL or ext clock
- DCE5: DCPLL or ext clock
Setting ATOM_PPLL_INVALID will cause SetPixelClock to skip
PPLL/DCPLL programming and only program the DP DTO for the
crtc virtual pixel clock.

The Xen changes were using DMA_ERROR_CODE which isn't defined on a few
platforms, however we reverted the Xen patch that caused use to try and
use this code path earlier in 2.6.39 cycle, so for now lets just force
the code to never take this path and allow it to build again on alpha.
The proper long term answer is probably to store if the dma_addr has
been assigned to alongside the dma_addr in the higher level code,
though I think Thomas wanted to rewrite most of this anyways properly.
