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

Internal display on my laptop isn't detected yet so modesetting doesn't
work, but at least I get vblank interrupts and backlight control.

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.

- Cleanup HEAD_MODE constants. These should be completely removed, now
that we have a proper notion of pipes and displays. But the DPMS code
still uses them, for now.
- Fix the ie_pipe command where width and height were swapped and
missing a +1 to show the actual videomode values
We need to assign PLLs to pipes and transcoders. The assignments on
previous generations were fixed, but now it's up to us to set it up.
Do the simplest thing for now: assign PLL1 to pipe A and PLL2 to pipe B.
- 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.
- The name for the registers were swapped
- The width and height were also swapped in one of them
- Remove some old #if 0 code that touched these registers but has been
disabled for a while.
LVDS panels must really be driven at their native resolution, otherwise
they will simply not work. This means we should basically never touch
the video timings on that side. We need to only set the source size in
the pipe configuration, and let the panel fitter figure out the scaling.
On my G45 laptop, this allows me to use non-native resolutions on the
laptop display. This also means when booting with a VGA display
connected, I do get a valid display on the internal panel (using the VGA
resolution). VGA still gets "out of range", so we're still not setting
up something there.
If I switch to VGA display in the BIOS, I get a working picture there
and garbage on the internal display, which is progress (before I would
get a black screen on the internal display)
Fixes#12723.
This reverts commit 4f059c1fc5.
From discussion on the mailing list, it seems I was correct the first time
and Broadwell is Gen8. The confusion comes from the SER5/SOC distinction,
which is not in the Linux driver, and I still don't know which one it really
belongs in.
