drm/amdkfd: Process-device data creation and lookup split
This patch splits the current kfd_get_process_device_data() to two
functions, one that specifically creates a pdd and another one which
just do lookup.
This is done to enhance the readability and maintainability of the code.

amdkfd: Add basic modules to amdkfd
This patch adds the process module and three helper modules:
- kfd_process, which handles process which open /dev/kfd
- kfd_doorbell, which provides helper functions for doorbell allocation,
release and mapping to userspace
- kfd_pasid, which provides helper functions for pasid allocation and release
- kfd_aperture, which provides helper functions for managing the LDS, Local GPU
memory and Scratch memory apertures of the process
This patch only contains the basic kfd_process module, which doesn't contain
the reference to the queue scheduler. This was done to allow easier code review.
Also, this patch doesn't contain the calls to the IOMMU driver for binding the
pasid to the device. Again, this was done to allow easier code review
The kfd_process object is created when a process opens /dev/kfd and is closed
when the mm_struct of that process is teared-down.
v3:
Removed kfd_vidmem.c file
Replaced direct mmput call to mmu_notifier release
Removed typedefs
Moved bool field to end of the structure
Added new kernel params for gart usage limitation
Added initialization of sa manager
Fixed debug messages
Remove support for LDS in 32 bit
Changed code to support mmap of doorbell pages from userspace
Added documentation for apertures
v4: Replaced RCU by SRCU for kfd_process list management
v5:
Move amdkfd from drm/radeon/ to drm/amd/
Rename kfd_aperture.c to kfd_flat_memory.c
Protect against multiple init calls
MQD size is H/W dependent so moved it to device info structure
Rename kfd_mem_obj structure's members
Use delayed function for process tear-down
