28476a5b13 gpu: nvgpu: create new nvgpu ioctl header
Move nvgpu ioctls from the many user space interface headers to a new
single nvgpu.h header under include/uapi. No new code or replaced names
are introduced; this change only moves the definitions and changes
include directives accordingly.

719923ad9f gpu: nvgpu: rename gpu ioctls and structs to nvgpu
To help remove the nvhost dependency from nvgpu, rename ioctl defines
and structures used by nvgpu such that nvhost is replaced by nvgpu.
Duplicate some structures as needed.

Update header guards and such accordingly.

bcf60a22c3 gpu: nvgpu: Add gk20a_fence type
When moving compression state tracking and compbit management ops to
kernel, we need to attach a fence to dma-buf metadata, along with the
compbit state.

To make in-kernel fence management easier, introduce a new gk20a_fence
abstraction. A gk20a_fence may be backed by a semaphore or a syncpoint
(id, value) pair. If the kernel is configured with CONFIG_SYNC, it will
also contain a sync_fence. The gk20a_fence can easily be converted back
to a syncpoint (id, value) parir or sync FD when we need to return it to
user space.

Change gk20a_submit_channel_gpfifo to return a gk20a_fence instead of
nvhost_fence. This is to facilitate work submission initiated from
kernel.
