The present code assumes that optimus is present whenever two
VGA (PCI_CLASS_DISPLAY_VGA) devices are present. This does not
seem to be the case of newer laptops with optimus, in which
case the nvidia gpu is a PCI_CLASS_DISPLAY_3D device.
Rework the logic so that we count both VGA and 3D devices,
when contemplating if optimus is present on the platform.

- Ilia's PMPEG improvements
- MSI fixes, and another attempt at enabling by default
- Initial GK208 support, just modesetting
- "Old" PM code gone, new infrastructure and various different stages of support (depending which chipset / ram type etc) is in its place. This includes support that goes beyond what the previous code was capable of. User control has been deliberately sabotaged, it's not safe to use still.
- Thermal management / fan control that's been present for a while is turned ON by default now.
- Misc other fixes that have accumulated
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (74 commits)
drm/nouveau/fb: implement various bits of work towards memory reclocking
drm/nouveau: implement a simple sysfs interface to new pm code
drm/nouveau/device: initial control object class, with pstate control methods
drm/nouveau/clk: implement power state and engine clock control in core
drm/nouveau/volt: implement voltage control in core
drm/nouveau/bios: parsing for various tables required for power management
drm/nouveau/perfmon: initial infrastructure to expose performance counters
drm/nouveau/bus: add interfaces/helpers for sequencer
drm/nouveau/bus: make external class definitions pointers

drm/nouveau/therm: no toggle fan control either if we can't guarantee no pwm connected
drm/nvc0/therm: allow fan control if we've killed the vbios ppwr ucode
drm/nouveau/therm: if no bios trip/linear info, default to perf-suggested speed
drm/nouveau/therm: add hook for clk to suggest fanspeed to therm
drm/nouveau/pwr: assign a subdev id for upcoming implementation
drm/nouveau/gpio: return different error code for not found vs invalid
drm/nouveau/drm/pm: remove everything except the hwmon interfaces to THERM
drm/nouveau/core: make all info-level messages silent for runtime pm

Matches the nv94-nvc0 commit with the same title. Doesn't fix a reported issue,
but NVIDIA use this ordering here too, so let's do it just in case.

This patch adds a way to define a custom delay when scanning for i2c devices
because the adt7473 sometimes doesn't like the default bitbanging udelay.

Certain combinations of hardware can't actually support the maximum
detected speed. Add a quirk list that lists pairs of hostbridge/chip pci
ids and the mode that they should work with.

This is what NVIDIA do on these chipsets, let's hope it works around
the reported MSI failures for us on NV86.
v2: updated to include G92, as per information provided by NVIDIA.
