I don't know why the DP/eDP is affected by the clock gating. But the test
shows that it really fixes the DP/eDP clock issue during enabling DP/eDP.

[Updated to only apply the workaround if the device has DP. We don't want
to do this on netbooks]

Introduce the eDP support into the driver.
This has been reworked a bit because kernel driver proper uses encoder/connectors
while the legacy Intel driver uses the old output stuff.
It also diverges on the backlight handling. The legacy Intel driver adds a panel
abstraction based upon the i915 one. It's only really used for backlight bits
and we have a perfectly good backlight abstraction which can extend instead.

Import the pieces we need in order to do DisplayPort. Don't wire them
up yet as there is work to do to integrate them.

Add the opregion support and bring us in line with the opregion functionality in the
reference driver code. We can't share this with i915 currently because there are
hardcoded assumptions about dev_priv etc in both versions.

In particular clean up the errata handling and correct the crtc masks. We do
this a bit differently using our device abstraction for neatness.
This doesn't address the ACPI opregion and hotplug plumbing, nor the IRQ related
changes that will need. It touches on backlight init but the full backlight
support is not in this change set.

Our current SDVO implementation is not working properly, so replace it with
a modified version of the i915. Further testing and debugging is needed to make
sure we can handle the different SDVO setups and wiring.

This provides the specific code for Poulsbo, some of which is also used for
the later chipsets. We support the GTT, the 2D engine (for console), and
the display setup/management. We do not support 3D or the video overlays.
In theory enough public info is available to do the video overlay work
but that represents a large task.
Framebuffer X will run nicely with this but do *NOT* use the VESA X
server at the same time as KMS. With a Dell mini 10 things like Xfce4 are
nice and usable even when compositing as the CPU has a good path to the
memory.
