Merge tag 'drm-amdkfd-next-2017-08-18' of git://people.freedesktop.org/~gabbayo/linux...

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
