intel_extreme: parse VBT device configs, use this to skip unused ports

* BDB version from 111
* for DDI from Gen9
* for HDMI and DisplayPort from Gen6
* use the first port to create the mode list
* also probe DDI Port A
* the aux channel helps to select the correct dp aux registers.

intel_extreme: improve brightness setting support

- Newer devices use a different layout for the backlight PWM registers
- Get the min brightness level from the BDB

intel_extreme: reduce use of display_mode where display_timing is enough

In most cases we don't need to use the complete display_mode struct and
we just need the timings. This will avoid future confusion between the
virtual width/height and the actual display timings, if we implement
scrolling someday.

intel_extreme: Improve PCH detection

* Detect PCH model based on ISA bridge and save
into shared info for later use.
* On CougarPoint PCH systems, assign pipes via
special CPT registers
* Drop HasPlatformControlHub as PCH should be
based on more than just generation.

intel_extreme: Properly use VBIOS panel mode

* Move current_mode into the accelerant as the
driver doesn't care.
* Record panel_mode in driver and present to accelerant
* eDP, if no EDID and mobile, leave edid incomplete.
Mode set should notice that and fall back to panel_mode

Some style fixes.

More work is needed for this new file to completely follow the style
guidelines. Also added several FIXMEs and TODOs.

This doesn't seem to break anything on my machine however, and was
confirmed to help by several users, so we may as well use it.

intel_extreme: add MSI support

intel_extreme and radeon_hd: some 64 bit fixes

intel_extreme: Drop odd semicolon causing gcc warnings

Remove the interrupt register block. These aren't actually identitiy mapped
(they are actually reversed), so introduce a find_reg() inline function to map
such regs individually instead. Should fix interrupt storms on SandyBridge.

* Rework how registers are accessed. Most registers are now grouped into
register blocks and we encode their block into the register definition. On
register access these blocks are then translated into the final address.
* Set up the register blocks for (G)MCH and PCH variants.
* Remove most SandyBridge code that was actually PCH specific and is now taken
care of automatically.
* This will temporarily break SandyBridge support again until the right
transcoders are actually programmed.

* Now phys_addr_t should be used where needed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37028 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed the way the device type is tested/set. There shouldn't be any functional
changes.
* Minor cleanup.

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.

* Added support for the G33 line of chips: mode setting and acceleration is working fine AFAICT.
* Implemented mapping the GTT area for i9xx chips other than the i965. This should also fix the
driver working with these chips at all.
* The memory used by the driver now take the GTT area into account - before the GTT could be
overwritten theoretically...
* Added fix for some i965 quirks from the X driver.
* Added some overlay definitions for the i965.
* Started support for G33 overlay (not complete yet).

Allocating additional memory should now work on the i965 as well (but bad things
will happen on earlier i9xx chips for now...). Not yet tested.

* The second open will now fail, too, in case the hardware could not be initialized
correctly.
* Got rid of this superfluous cookie stuff - either the VFS behaves correctly, or
we're screwed anyway.
* Made adding debugger commands optional depending on if DEBUG_COMMANDS is defined
or not.
* Minor other cleanup.

headers into intel_extreme_private.h.
