:intel_extreme: only offer backlight control in screenpres on laptops.

intel_extreme: implement get_preferred_mode for vbt on mobile

this avoids searching in edid information in this case.

intel_extreme: remove unhandled generation defines

- 7xx (1st gen) has no driver in Haiku or is handled by the intel_810 driver
- PowerVR has no driver in Haiku

So there is no point in having those in the intel_extreme driver.

While I'm at it, fix the video timing/resolution constraints for
sanitize_video_mode.

Support for configuring screen backlight

Accelerant interface:
Introduce new hooks B_SET_BRIGHTNESS and B_GET_BRIGHTNESS. Brightness is
a float in the 0..1 range.

App_server:
Forward brightness things between BScreen and the accelerant.

intel_extreme:
Implement the hooks. Note that this only works for laptop panels, but
the driver will pretend to support it in other cases as well.

Screen preferences:
If the accelerant supports the B_GET_BRIGHTNESS hook, allow to set
brightness with a slider. Otherwise, the slidere is hidden and these
changes aren't visible.

intel_extreme: Rework PLL and id PineView as PIN

intel_extreme: Rework card identification defines

* Be more verbose on flag type
* Add additional groups
* Add additional families
* Correctly assign later models

intel_extreme: Intial work for ValleyView support

* No impact to non-ValleyView chipsets
* Bump some register locations for VLV
* Only have HDMI port to test with on my ValleyView GPU
and our driver seems to be missing all HDMI and
sideband functionality.
* As ValleyView chipsets seem to be UEFI only, we don't
have VESA fallback, so this shouldn't cause regressions.
(unless we get UEFI framebuffer support)

intel_extreme: Add IvyBridge fixups

* Add initial clock gating fix (may need tweaking)

* Add a couple more SandyBridge IDs. They might work, but I can't test them.
* Also add the definitions and some specifics for IronLake (ILK), but keep the
IDs disabled as at least the one version I can test with doesn't work yet.

Style cleanups only, no functional change.
* Make the pointer style consistent accross all components, which should make it
easier when working all over the place.
* 80 char limits.

* Add preliminary support for one SandyBridge mobile integrated graphics device
(the one in my new ThinkPad X1). The PLL is still off a bit so it has a few
blurry stripes, but EDID and mode setting basically works.
* Starting with IronLake the north/south bridge or (G)MCH/ICH setup was moved
into a platform control hub (PCH) which means that many registers previously
located in the GMCH are now in the PCH and have a new address.
* I'm committing this mostly because this way the additions are more easy to
follow. It is a bit messy and I'll clean it up more and possibly make it a
bit more generic. Also most of these changes actually apply to IronLake and up
and aren't SandyBridge specific, so a few of those additions will still get a
broader scope and new chips will be added.

Work in progress (might not work for you yet):
* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.

* commented out span acceleration function, since it doesn't seem to work
* added mode for 1440x900, the numbers are just guessed, but work fine
with my monitor (after some fiddling), would be best to have some common
VGA communication code for all drivers to use and auto-detect the preferred
mode of the monitor
* messed around with the overlay brightness and contrast values to give
good looking video

* Implemented hardware cursor support.
* Turns out cursor handling is simpler as originally thought, so I could remove its
physical mapping - it's still put into the shared area, though, although that isn't
needed for this chip (but could eventually simplify the handling of other generations
of this chip).

use it (which isn't really that bad).
* B_SCREEN_TO_SCREEN_BLIT is now working as intended, so we can finally move
windows and scroll at decent speed :-)
* Implemented a simple version of B_WAIT_ENGINE_IDLE for now.

reason I need to investigate some day (maybe tomorrow :)).
