Replaces the piece-by-piece (in response to NV_DEVICE ctor args) device
contruction with a once-off all-or-nothing approach, eliminating some
tricky refcounting issues.  The partial device init capability was only
required by some tools, and has been moved to probe time instead.

Temporarily removes a workaround for some boards where we need to fiddle
with AGP registers before executing the DEVINIT scripts.  A later commit
in this series reinstates it.

A future commit will hide the platform/pci specifics from nvkm_device,
but it's still very useful in a lot of places to have access to the
Linux device struct.

Will be used in upcoming commits to remove the need for lookup/runtime
type-checking functions when accessing foreign subdevs.

MSI interrupts appear to not work for nv46 based cards. Change the mc
subdev oclass for these cards from nv44 to nv4c, the nv4c mc code is
identical to the nv44 mc code except that it does not use msi
(it does not define a msi_rearm callback).

These signals and sources have been reverse engineered from CUPTI
(Linux). Graphics signals exposed by PerfKit (Windows only) will be
added later. I need to reverse engineer them and it's a bit painful.

This commit also adds a new class for GF108 and GF117.

Uncertain whether the GPC pack change is due to a newer driver version,
or a legitimate difference from GM204.  My GM204 has broken vram, so
can't currently try a newer binary driver on it to confirm.

Turns out the PTHERM part of this dance is bracketed by the same PMU
fiddling that occurs on GK104/6, let's assume it's also PGOB.

GK20A does not have dedicated RAM, thus having a RAM device for it does
not make sense. Move the contiguous physical memory allocation to
instmem.
