Now that the base struct drm_gem_object has a reservation_object, use it
and remove the private BO one.

The TFU can copy from raster, UIF, and SAND input images to UIF output
images, with optional mipmap generation. This will certainly be
useful for media EGL image input, but is also useful immediately for
mipmap generation without bogging the V3D core down.
For now we only run the queue 1 job deep, and don't have any hang
recovery (though I don't think we should need it, with TFU). Queuing
multiple jobs in the HW will require synchronizing the YUV coefficient
regs updates since they don't get FIFOed with the job.
v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
why TFU is AUTH, clarify the syncing docs, drop the unused TFU
interrupt regs (you're expected to use the hub's), don't take
&bo->base for NULL bos.
v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
on drm_sched_job_cleanup() changes.

Everything in the flush code path (i.e. waiting for SW queue
to become empty) names with *_flush()
and everything in the release code path names *_fini()
This patch also effect the amdgpu and etnaviv drivers which
use those functions.
v2:
Also pplay the change to vd3.

into drm-next
Main changes for 4.18. I'd like to do a separate pull for vega20 later
this week or next. Highlights:
- Reserve pre-OS scanout buffer during init for seemless transition from
console to driver
- VEGAM support
- Improved GPU scheduler documentation
- Initial gfxoff support for raven
- SR-IOV fixes
- Default to non-AGP on PowerPC for radeon
- Fine grained clock voltage control for vega10
- Power profiles for vega10
- Further clean up of powerplay/driver interface
- Underlay fixes
- Display link bw updates
- Gamma fixes
- Scatter/Gather display support on CZ/ST
- Misc bug fixes and clean ups
[airlied: fixup v3d vs scheduler API change]

This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.
V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme. This massively changes the
GEM behavior, so I've forked off to a new driver.
v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild
test robot. Drop personal git link from MAINTAINERS. Don't
double-map dma-buf imported BOs. Add kerneldoc about needing MMU
eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup
to mmap time. Use drm_dev_init instead of _alloc. Use
ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage,
since we don't modeset. Switch page tables back to WC (debug
change to coherent had slipped in). Switch
drm_gem_object_unreference_unlocked() to
drm_gem_object_put_unlocked(). Simplify overflow mem handling by
not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
other ioctls.
