Another reference to raw_edid field of struct drm_display_info was added in
gma500 while the whole field was being removed, causing build
failure. Remove the hopefully last references to raw_edid.

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.
