This patch adds two new functions to the kfd-->kgd interface:
init_gtt_mem_allocation, which allocate a large enough buffer on the amdkfd
needs, such as mqds, hpds, kernel queue, fence and runlists. This function
is only called once per GPU device. The size of the allocated buffer is
based on the maximum number of HSA processes and maximum number of queues
per HSA process (two amdkfd kernel module parameters).
free_gtt_mem, which frees a buffer that was allocated on the gart aperture.

This patch adds three new functions to the kfd2kgd interface:
- hqd_sdma_load() - Loads SDMA mqd to a H/W SDMA hqd slot. Used only in no HWS
mode.
- hqd_sdma_is_occupied() - Checks if an SDMA hqd slot is occupied. Used only
in no HWS mode.
- hqd_sdma_destroy() - Destructs and preempts the SDMA queue assigned to
that SDMA hqd slot. Used only in no HWS mode.
These functions are needed to support SDMA queues scheduling when using no HWS
mode (used for debug or bring-up).

Next batch of atomic work. Most important is the propertification from Rob
and the nth iteration of the actual atomic ioctl originally from Ville.
Big differences compared to earlier revisions:
- Core properties are now fully handled by the core, drivers can only
handle driver-specific properties.
- Atomic props&ioctl are opt-in per file_priv, userspace needs to
explicitly ask for it (like universal plane support).
- For now all hidden behind the atomic module option until this has
settled a bit.
- Atomic modesets are currently not possible since the exact abi for how
to handle the mode property is still under discussion.
Besides this some cleanup patches from me and the addition of per-object
state to global state backpointers to simplify drivers.

- Complete overhaul to the main IOCTL function, kfd_ioctl(), according to
drm_ioctl() example. This includes changing the IOCTL definitions, so it
breaks compatibility with previous versions of the userspace. However,
because the kernel was not officialy released yet, and this the first
kernel that includes amdkfd, I assume I can still do that at this stage.

We do not need to track the state of the IPU DI's clock flags by having
each display bridge calling back into imx-drm-core, and then back out
into ipuv3-crtc.c.
ipuv3-crtc can instead just scan the list of encoders to retrieve their
type, and build up a picture of which types of encoders are attached.
We can then use this information to configure the IPU DI clocking mode
without any uncertainty - if we have multiple bridges connected to the
same DI, if one of them requires a synchronous DI clock, that's what we
must use.

always create a context for every filp, this means that individual
processes can fine tune their behaviour even if they do not explicitly
create a context.

It is platform/output depenedent when exactly the pipe will start
running. Sometimes we just need the (cpu) pipe enabled, in other cases
the pch transcoder is enough and in yet other cases the (DP) port is
sending the frame start signal.
In a perfect world we'd put the drm_crtc_vblank_on call exactly where
the pipe starts running, but due to cloning and similar things this
will get messy. And the current approach of picking the most
conservative place for all combinations also doesn't work since that
results in legit vblank waits (in encoder->enable hooks, e.g. the 2
vblank waits for sdvo) failing.
Completely going back to the old world before

drm/i915: Use generic vblank wait
isn't great either since screaming when the vblank wait work because
the pipe is off is kinda nice.
Pick a compromise and move the drm_crtc_vblank_on right before the
encoder->enable call. This is a lie on some outputs/platforms, but
after the ->enable callback the pipe is guaranteed to run everywhere.
So not that bad really. Suggested by Ville.
v2: Same treatment for drm_crtc_vblank_off and encoder->disable: I've
missed the ibx pipe B select w/a, which also has a vblank wait in the
disable function (while the pipe is obviously still running).
