This adds support for enabling automatic clockgating on nvidia GPUs for
Kepler1. While this is not technically a clockgating level, it does
enable clockgating using the clockgating values initially set by the
vbios (which should be safe to use).

This introduces two therm helpers for controlling basic clockgating:
	nvkm_therm_clkgate_enable() - enables clockgating through
	CG_CTRL, done after initializing the GPU fully
	nvkm_therm_clkgate_fini() - prepares clockgating for suspend or
	driver unload

A lot of this code was originally going to be based off of fermi;
however it turns out that while Fermi's the first line of GPUs that
introduced this kind of power saving, Fermi requires more fine tuned
control of the CG_CTRL registers from the driver while reclocking that
we don't entirely understand yet.

For the simple parts we will be sharing with Fermi for certain however,
we at least add those into a new subdev/therm/gf100.h header.

Forked from GP107 implementation. Secboot/gr left out as we don't have
signed blobs from NVIDIA in linux-firmware.

(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
       so not able to 100% confirm that no other changes from GP107
       are needed.  Quick testing shows it seems to work well enough
       for display.  Due to NVIDIA dragging their heels on getting
       signed firmware to us, this is the best we can do for now.

The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP
and PCI varieties, rather than a core PCIE chip with a bridge for
AGP/PCI as necessary. As a result, it appears that the MMU is also
non-functional. For AGP cards, the vast majority of the NV4A lineup,
this worked out since we force AGP cards to use the nv04 mmu. However
for PCI variants, this did not work.

Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for
the suggestion. This should be a no-op for NV4A AGP boards, as they were
using it already.
