amdkfd:

radeon:
- ACPI ref count fix
- HDA audio notifier support
- Move Kconfig into radeon directory
UAPI:
- Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI.
These are used internally in the driver to align location based memory coherency
requirements from memory allocated in the KFD with how we manage GPUVM PTEs. They
are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now.
They are just used internally in the kernel driver for now for existing KFD memory
allocations. So a change to the UAPI header, but no functional change in the UAPI.
