On >=nv50, userspace would still end up allocating pushbufs in GART.

This patch adds instructions to ctxprog and by doing, impacts context
switching performance.  My testcase showed a 1% performance cost using
glxgears that is a context-switch bound application.

Please test and report bugs/performance/power/other.

Many thanks to Maxim Levitsky for his dedicated work on lowering power
consumption with nouveau.

More patches are coming thanks to his work:

Written from observations of my NVD9's vbios, completely untested due to
my NVD9 lacking actual DisplayPort connectors..

Will need to be able to distinguish 2.0/2.1 from 3.0 soon.  Also, move
the vbios parsing to nouveau_dp where it belongs.

The caller is now responsible for parsing its own lists (or whatever) of

We don't use these by default anymore, and there's been complaints from a
number of places thinking that the firmware blobs are required still.

Not 100% perfect yet, but a good start towards what it'll look like in the
end.

Actually seems stable on a NV44 I have here, as much as running around OA
for a fair amount of time constantly switching between performance levels
can prove..

My NV49 isn't quite so happy, and semaphores mess up somehow (sometimes) as
a result of the memory reclocking.

This changes the meaning of what we reported as "core" clock previously.

The shader/rop units are allegedly supposed to be run at the base clock
listed in the perf table, while the geometric clock can be bumped from
this value on some boards.

So that we can report both, we'll report the base clock as "shader" (since
the shaders *do* run at it), and the geometric clock as "core".

The HW will only accept the DMA_FROM_MEMORY class for DMA_SEMAPHORE without
asking the driver to intervene.

It appears that semaphores will work correctly even without DMA_IN_MEMORY,
so lets avoid the large amount of interrupts generated by x-chan sync.

The clock_get() hook returns KHz, not Hz.

Also fixed to use crystal freq from dev_priv.
