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.

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.

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.

HSA thunk API is currently reporting engineering name to MarketingName
and returning NULL when querying for AMDName.
-Change current name reporting from MarketingName to AMDName.
-Use libpci to get MarketingName

KFD may not be able to provide the precise VM fault address and status.
This flag will indicate whether the event data has the fault details

The Runtime requested this information so they can tell easily
whether a pointer is part of HSA shared address space or not.

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.
Change-Id: I7e9c6437b023bb23ec9578737f8534e9453589b9
- 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.
