The drm_gem_shmem_create() returns error pointers and v3d_bo_create() is
also supposed to return error pointers.

The new shmem helpers from Noralf and Rob abstract out a bunch of our
BO creation and mapping code.
v2: Use the new sgt getter, and flag pages as dirty before freeing.
v3: Remove the mismatched put_pages.

vmas was from the previous model of page table management (one per
fd), and vaddr was left over from vc4.

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

We always decrement at GEM free, so make sure we increment at GEM
creation for dma-bufs.

v3d_bo_get_pages() checks this to decide to map the imported buffer
instead of the backing shmem file. The caller was about to set this
value anyway, and there's no error path in between. Ideally we
wouldn't even allocate the shmem file for our imports, but that's a
more invasive fix.

Instead of converting an errno into a vm_fault_t ourselves, use
vmf_insert_mixed() which returns a vm_fault_t directly.

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.
