The set will be replaced with a wait on the same flag by a subsequent
commit in order to halt a ctxprog's execution temporarily.

nv04_sgdma_bind binds the same page multiple times on

Not cleaning after alloc failure would result in crash on destroy,
because nouveau_sgdma_clear assumes "ttm_alloced" to be not null when
"pages" is not null.

It may not be necessary to fail in certain cases (such as failing to idle)
on module unload, whereas on suspend it's important to ensure a consistent
state can be restored on resume.

It's completely pointless to save the PGRAPH context when destroying a
channel, so don't bother.
This commit should also fix kernel.org bug 39422, where the DRM channel
state was incorrectly being saved because we left PGRAPH FIFO access
enabled while running the ctxprog.

If the connector table is lying, which it often does on the boards of a
particular manufacturer, we may end up doing the wrong thing. Listen
to the encoder table instead, it's more reliable.

If we return due to an unknown chipset in

memory allocated to 'pgraph'.

drm_pci_device_is_pcie duplicates the funcationality of pci_is_pcie.
Convert callers of the former to the latter. This has the side benefit
of removing an unnecessary search in the PCI configuration space due to
using a saved PCIe capability offset.

'drm/nouveau: rework vram init/fini ordering a little' changed
the order of instmem.init() and nouveau_mem_vram_init() which
resulted in using ramin_rsvd_vram before it was calculated and
failing to init any accel on pre-NV50 cards.
Since it's only used on <NV50 just calculate it where it's needed
and leave it as default 0 for NV50.
