drm/i915: fix up tiling/fence reg setup on i8xx class hw
This fixes all the tiling problems with the 2d ddx. glxgears still doesn't work.
Changes:
- fix a copy&paste error in i8xx fence reg setup. It resulted in an at most a
512KB offset of the fence reg window, so was only visible sometimes.
- add tests for stride and object size constrains (also for i915 and 1965 class
hw). Userspace seems to have an of-by-one bug there, which changes the fence
size by at most 512KB due to an overflow.
- because i8xx hw is quite old (and therefore not as well-tested) I left 2 debug
WARN_ONs in the i8xx fence reg setup code to hopefully catch any further
overflows in the bit-fields. Lastly there's one small change to make the
alignment checks more consistent.

efifb: dmi set video type
The current logic for dmi matching in efifb does not allow efifb to load
on all hardware that we can dmi match for.
For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a
Apple (MacBook) and EFI framebuffer driver will not load (you will have no
video). This specific hardware is efi v1.10, so we have UGA and not GOP.
Without special bootloader magic (i.e. extra elilo patches for UGA
graphics detection) no screen info will be passed to the kernel and as a
result efifb will not load.
This patch allows the dmi match to happen by moving it to earlier in
efifb_init, and sets the video type (in set_system) so that efifb can load
when we have a valid dmi match and already know the specifics of the
hardware.
Without this patch the efifb driver will fail to load in the event screen
info is not found and passed in by the bootloader, being that we will
never get to look for a dmi match. A primary reason for matching with dmi
is because not all bootloaders detect the video info properly. The
solution is that in the event of a dmi match, we should set
screen_info.orig_video_isVGA. Most bootloaders fail to set screen info on
Apple hardware, and this is a big problem for people who use Apple
hardware.
Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the
issue, the dmi match now works, EFI framebuffer now loads and video works.

tridentfb: delete acceleration Kconfig option
Remove Kconfig option for tridentfb acceleration. The acceleration can be
switched off with modules "noaccel" parameter.
The acceleration for Trident chips was fixed in the 2.6.27 kernel.
Also, add CyberXXX and CyberBlade names to Kconfig option's name. It should
make easier to find the tridentfb choice for cyblafb driver's users. The
cyblafb driver has been replaced by the tridentfb driver.

fbdev: remove cyblafb driver
A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.
Changes to the tridentfb driver:
- FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter
for scrolling which is faster than color expansion on Cyberblade
chipsets. The blitter is slower on a discrete Blade3D core. Use the
blitter for scrolling in the tridentfb only for integrated Blade3D
cores. Now, scrolling speed is about equal for the tridentfb and the
cyblafb.
- a copyright notice addition is done on request of Jani Monoses (the
first author of the tridentfb).

Together these can help us to differentiate between similiar setups.
This patch adds the proper way of grabbing both those values and save them
for future reference (in order to decide what functions a card supports,
e.g acceleration).

cirrusfb: various Laguna fixes
- The Laguna GD5465 (AGP) has one register more than non-AGP chips.
Recognize the AGP version and write a tile control register only on the
AGP version. Tested only on an AGP card.
- Bump up RAMDAC frequencies after X11 code. This allow to drive a flat
panel resolution 1680x1050 at 16bpp from the 4MB card.
- Fix screen start address overflow bits on Laguna cards (CRT1D
register).

cirrusfb: check_var improvements
Break cirrusfb_decode_var() function into two parts:
cirrusfb_check_pixclock() which can be called from the
cirrusfb_check_var() aand merge rest into the cirrusfb_set_par_foo().
This allows rejecting modes with too high pixclock before before any
change to hardware state (and a console is messed up).
Also, fix RGB field's lengths for 8bpp modes to correct ones so X11 works
with fbdev driver with cirrusfb.
Kill some redundant function calls or register loads.

Various improvements to the code:

- move the cirrusfb_ops structure

- move cirrusfb_init() to kill
forward declaration
- kill register loads done already
in the init_vgachip()
- kill assigments done by higher
layer in the cirrusfb_pan_display()
- do not overwrite line pitch bit in
the CL_CRT1D register
- kill btype variables if they were
used only once or twice
- add cpu_relax() in the busy waiting
