Later changes will depend on being able to pull down CRTCs etc with the
master display state still intact.

This will be used instead of storing a heap of per-head data (such as evo
channels) in nvd0_display in some other way.

Currently unused, and rudimentary.  Lots to figure out here still, but
this is sufficient for what disp will need.

disp is going to need to be able to create more specific dma objects
than was previously possible.

The hardware dmaobj format completely changed in GF119, so these will
need a separate implementation.

Otherwise when nvc0- gains a bind() method (disp needs it), the fifo
engine will attempt to create a dma object for the push buffer, which
is unnecessary on fermi.

The only sane place to put these checks is in the bind method itself,
and have it unconditionally called from wherever it might be needed.

Simplifies things a little, and currently no reason to need
chipset-specific dmaobj constructors.

Will be required by future work.  Make the API change now to catch any
(but hopefully none) unexpected fallout.

This used to output the function name, now doesn't, so just looks
