NVIDIA also appear to use the same class on Fermi/Kepler for PPP.

Will allow use of the engine if firmware (nvXX_fuc086) provided.

Later chipsets use falcon anyway, and I can't currently see a good need
for a shared base class.

PPP will get the same treatment once Maarten's patches are merged.

No support for the class yet, but will be pulled in with Maarten's Fermi
vdec patches.  The Kepler PPP class is identical.

Previously, if either vram/gart handles were specified as ~0, the ioctl
call would fail.  In order to hack engine selection into the ioctl for
kepler, we now define (fb_ctxdma_handle == ~0) to mean "engine mask is
in tt_ctxdma_handle".

This approach also allows new userspace to detect lack of support for
non-PGRAPH channels on older kernels.

we need to use pm ops for that, so first convert the driver to using pm ops
