Problem:
Handle all DMA IOMMU group related dependencies before the
group is removed. Those manifest themself in that when IOMMU
enabled DMA map/unmap is dependent on the presence of IOMMU
group the device belongs to but, this group is released once
the device is removed from PCI topology.
Fix:
Expedite all such unmap operations to pci remove driver callback.
v5: Drop IOMMU notifier and switch to lockless call to ttm_tt_unpopulate
v6: Drop the BO unamp list
v7:
Drop amdgpu_gart_fini
In amdgpu_ih_ring_fini do uncinditional check (!ih->ring)
to avoid freeing uniniitalized rings.
Call amdgpu_ih_ring_fini unconditionally.
v8: Add deatiled explanation

nbio ras is not managed by gpu driver when gpu is
connected to cpu through xgmi. split nbio callbacks
into ras and non-ras ones so gpu driver only
initializes nbio ras callbacks when it manages
nbio ras.

The preinstall callback didn't do anything because not all
of the IPs were initialized when it was called.
Move the postinstall setup into sequence in the driver.
The uninstall callback disabled all interrupt source, but
it got called too late in the driver sequence and caused problems
with IPs who already freed the relevant data structures. Move
the call into the right place in the driver sequence.

With instantaneous high precision vblank timestamping
that updates at leading edge of vblank, a cooked hw
vblank counter which increments at leading edge of
vblank, and reliable page flip execution and completion
at leading edge of vblank, we should meet the requirements
for fast/immediate vblank irq disable/enable.
Testing on Linux-4.12-rc5 + drm-next on a Radeon R9 380
Tonga Pro (DCE 10) with timing measurement equipment
indicates this works fine, so allow immediate vblank
disable for power saving.
For debugging in case of unexpected trouble, booting
with kernel cmdline option drm.vblankoffdelay=0
(or echo 0 > /sys/module/drm/parameters/vblankoffdelay)
would keep vblank irqs permanently on to approximate old
behavior.
