The nouveau_wait_for_idle() call should hopefully not have been actually
necessary, we *do* wait for the channel to go idle already.  If it's
an issue somehow, the chipset-specific hooks can wait for idle themselves
before taking the lock.

Much nicer to do that nv50, the code was pretty much written to expect
such a change in the future.

This needs a massive cleanup, but to catch bugs from the interface changes
vs the engine code cleanup, this will be done later.

There's lots of more-or-less independant engines present on NVIDIA GPUs
these days, and we generally want to perform the same operations on them.
Implementing new ones requires hooking into lots of different places,
the aim of this work is to make this simpler and cleaner.

NV84:NV98 PCRYPT moved over as a test.

Improves the parsing of the memory timing table on NV50-NV98revA1 chipsets.

Added stepping to drm_nouveau_private to make sure newer NV98 (105M) is
zero rather than incorrect.

So in a lot of modern systems, a GPU will always be below a parent bridge that won't share with any other GPUs. This means VGA arbitration on those GPUs can be controlled by using the bridge routing instead of io/mem decodes.

The problem is locating which GPUs share which upstream bridges. This patch attempts to identify all the GPUs which can be controlled via bridges, and ones that can't. This patch endeavours to work out the bridge sharing semantics.

When disabling GPUs via a bridge, it doesn't do irq callbacks or touch the io/mem decodes for the gpu.

The previous commit to move the parsing into the core drm created a
new situation and a soft dependency on the CONFIG_FB. We really don't
want to make this a hard dependency so just wrap the one place that
actually needs an fb symbol.

In the absence of configuration data for providing the fixed mode for
a panel, I would like to be able to pass such modes along a separate
module paramenter. To do so, I then need to parse a modeline from a
string, which drm is already capable of. Export that capability to the
drivers.
