Previously kfd device is used to map memory for CPU access.
However this is not compatible with how TTM handles CPU mapping
on eviction - memory won't be unmapped and remapped on restore.
This fixes the issue by mmapping memory using DRM render device.
This patch requires a coordinated kernel driver change to work.
To make it compatible with old kernel driver, some temporary codes
are included. Once the coordinated kernel driver is checked in,
the temporary codes can be removed.

The KFD implementation has been removed and will not be upstreamed.
This API has been superseded by hsaKmtRegisterGraphicsHandleToNodes.

For items in HsaQueueInfo, control stack information comes from KFD, CU
mask information is maintained in Thunk, and others (queue detail error
and queue type extended) are ignored (value = 0) at this point.

This change breaks the ABI, and aligns it with the upstream ABI.
It also fixes some ioctl structures that are not 64-bit safe and
consolidates ioctl numbers.

Allocate doorbells for dGPUs in the SVM aperture and map them for
GPU access. This is necessary to allow GPU-initiated submissions to
user mode queues.
Depends on new doorbell BO allocation flag in KFD.

Add two pointer attributes APIs:
hsaKmtQueryPointerInfo - allow the user to query the memory information
using a pointer. This pointer can point to any address inside the
range known to HSA.
hsaKmtSetMemoryUserData - allow the user to attach data to a pointer to
add memory tracking information. This pointer must match the start
address of a memory allocation or registration.
TODO: This patch implements support on dGPU. Needs to add APU.

Allocate SVM address space for the registered memory and use new
userptr support in KFD to create a system memory BO associated with
the given user pointer. Map this BO at the SVM address for CPU
access.
MapMemoryToGPU can be used with the registered user pointer and
will return the SVM address as alternate GPUVA.

Fix hsaKmtRegisterMemory to be a no-op for now and move the multi-GPU
implementation to hsaKmtRegisterMemoryToNodes. Make GPU memory mappings
of host memory visible to all GPUs by default. Device memory is still
visible to the allocating GPU only by default (but can be overridden
with hsaKmtRegisterMemoryToNodes for experimenting with P2P).

HSA_ENGINE_ID in Perforce added ui32 to the typedef while in Git it doesn't.
This causes conflicts to RT applications. Decision being made is to change Git
to match Perforce.

- Replace HSAuint32 with HSA_ENGINE_ID for EngineId type so it explicitely
presents version information for ucode and GfxIP
- Created a GfxIP lookup table to pass the version information. This lookup
searches for matching device ID.
