Handle asic specific table to hw mappings in
combios_setup_i2c_bus() directly. This allows us
to remove most of the combios quirks and clean up
the i2c bus setup.

Previously we added i2c buses as needed when enumerating connectors
power management, etc. This only exposed the actual buses used and
could have lead to the same buse getting created more than once if
one buses was used for more than one purpose. This patch sets up
all i2c buses on the card in one place and users of the buses just
point back to the one instance.

- buffer offsets in the base regs are 256b aligned so
shift properly when comparing, fixed by Andre Maasikas
- mipmap size was calculated wrong when nlevel=0
- texture bo offsets were used after the bo base address was added
- vertex resource size register is size - 1, not size

(For some reason I thought that went in ages ago ...)
This fixes support for PCI domains in what should hopefully be a backward
compatible way along with a change to libdrm.
When the interface version is set to 1.4, we assume userspace understands
domains and the world is at peace. We thus pass proper domain numbers
instead of 0 to userspace.
The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
ignoring domains in the later case (well, except on alpha of course)

sil164 and friends are the most common, usually they just need to be
poked once because a fixed configuration is enough for any modes and
clocks, so they worked without this patch if the BIOS had done a good
job on POST. Display couldn't survive a suspend/resume cycle though.
Unfortunately, BIOS scripts are useless here.

Previously nouveau_mem_reset_agp() was only disabling AGP fast writes
when coming back from suspend. However, the "locked out of the card
because of FW" problem can also be reproduced on init if you
unload/reload nouveau.ko several times. This patch makes the AGP code
reset FW on init.

This makes it easier to see how this is working, and lets us transfer the
EDID in blocks of 16 bytes.
The primary reason for this change is because debug logs are rather hard
to read with the hundreds of single-byte auxch transactions that occur.

This restricts the use of the big kernel lock to the i830 and i810
device drivers. The three remaining users in common code (open, ioctl
and release) get converted to a new mutex, the drm_global_mutex,
making the locking stricter than the big kernel lock.
This may have a performance impact, but only in those cases that
currently don't use DRM_UNLOCKED flag in the ioctl list and would
benefit from that anyway.
The reason why i810 and i830 cannot use drm_global_mutex in their
mmap functions is a lock-order inversion problem between the current
use of the BKL and mmap_sem in these drivers. Since the BKL has
release-on-sleep semantics, it's harmless but it would cause trouble
if we replace the BKL with a mutex.
Instead, these drivers get their own ioctl wrappers that take the
BKL around every ioctl call and then set their own handlers as
DRM_UNLOCKED.

This connector attribute allows you to enable or disable underscan
on a digital output to compensate for panels that automatically
overscan (e.g., many HDMI TVs). Valid values for the attribute are:
off - forces underscan off
on - forces underscan on
auto - enables underscan if an HDMI TV is connected, off otherwise
default value is auto.

Logic was:

Should be:
if (mode0 && mode1)
else if (mode0)
