drm/tegra: Changes for v4.14-rc1

This contains a couple of fixes and improvements for host1x, with some
preparatory work for Tegra186 support.

The remainder is cleanup and minor bugfixes for Tegra DRM along with
enhancements to debuggability.

There have also been some enhancements to the kernel interfaces for
host1x job submissions and support for mmap'ing PRIME buffers directly,
all of which get the interfaces very close to ready for serious work.

* tag 'drm/tegra/for-4.14-rc1' of git://anongit.freedesktop.org/tegra/linux: (21 commits)
  drm/tegra: Prevent BOs from being freed during job submission
  drm/tegra: gem: Implement mmap() for PRIME buffers
  drm/tegra: Support render node
  drm/tegra: sor: Trace register accesses
  drm/tegra: dpaux: Trace register accesses
  drm/tegra: dsi: Trace register accesses
  drm/tegra: hdmi: Trace register accesses

  drm/tegra: dc: Use unsigned int for register offsets
  drm/tegra: Fix NULL deref in debugfs/iova
  drm/tegra: switch to drm_*_get(), drm_*_put() helpers
  drm/tegra: Set MODULE_FIRMWARE for the VIC
  drm/tegra: Add CONFIG_OF dependency
  gpu: host1x: Support sub-devices recursively
  gpu: host1x: fix error return code in host1x_probe()
  gpu: host1x: Fix bitshift/mask multipliers
  ...

this cycle has been fairly calm in etnaviv land with most of the action
happening on the userspace side.

Notable changes:
- Improvements to CONFIG option handling to make it harder for users to
shoot themselves in the foot due to kernel misconfiguration.
- Tweaked GEM object population, so that userspace can take considerate
action when memory allocation fails, rather than waking the raging OOM
killer beast.

* 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux:
  drm/etnaviv: switch GEM allocations to __GFP_RETRY_MAYFAIL
  drm/etnaviv: don't fail GPU bind when CONFIG_THERMAL isn't enabled
  drm/etnaviv: switch to drm_*{get,put} helpers
  drm/etnaviv: select CMA and DMA_CMA if available
  drm/etnaviv: populate GEM objects on cpu_prep
  drm/etnaviv: reduce allocation failure message severity
  drm/etnaviv: don't trigger OOM killer when page allocation fails

This is the amdkfd pull request for 4.14 merge window.
AMD has started cleaning the pipe and sending patches from their internal
development to the upstream community.

The plan as I understand it is to first get all the non-dGPU patches to
upstream and then move to upstream dGPU support.

The patches here are relevant only for Kaveri and Carrizo.

The following is a summary of the changes:
- Add new IOCTL to set a Scratch memory VA
- Update PM4 headers for new firmware that support scratch memory
- Support image tiling mode
- Remove all uses of BUG_ON
- Various Bug fixes and coding style fixes

Since DRM IOCTL's are lockless, there is a chance that BOs could be
released while a job submission is in progress. To avoid that, keep the
