This patch does some re-org on the device_queue_manager structure. It takes out
all the function pointers from the structure and puts them in a new structure,
called device_queue_manager_ops. Then, it puts an instance of that structure
inside device_queue_manager.
This re-org is done to prepare the DQM module to support more than one AMD APU
(Kaveri).

Instead of creating a BUG if trying to free a NULL GART sub-allocation object,
just return 0 (success).
This is done to mirror behavior of kfree.

This patch rewrites destroy_queue_nocpsch() as the current logic that is
implemented in the function is completely flawed.
This function is used only in non-HWS mode.

The MQDs for CI and VI are different. Therefore, the MQD manager module need to
be H/W specific.
This patch splits the current MQD manager into three files:
- kfd_mqd_manager.c, which contains common functions and initializes the
specific mqd manager module according to the H/W
- kfd_mqd_manager_cik.c, which contains Kaveri specific functions. This is
basically the old kfd_mqd_manager.c
- kfd_mqd_manager_vi.c, which will contain VI specific functions. Currently it
is not implemented except for returning NULL on initialization.

This patch adds a new property to kfd_device_info structure. That structure
holds information that is H/W specific.
The new property is called asic_family and its purpose is to distinguish
between different asic families in amdkfd operations, mainly in QCM (queue
control & management)
This patch also adds a new enum, to select different ASICs. We set the current
kfd_device_info instance as Kaveri and create a new instance which describes
the new AMD APU, codenamed 'Carrizo'.

As the MQD types are common across all AMD GPUs/APUs, let's remove the CIK part
from the name.

This patch adds new fields to the queue_properties structure. The new fields
are relevant only for queues running on AMD GPU VI architecture.
The eop_ring_buffer_address and eop_ring_buffer_size describe an
end-of-pipe queue which is assigned to the MQD. In CI, the EOP queue was per
pipeline and in VI it is per queue.
The ctx_save_restore_area_address and ctx_save_restore_area_size describe a
memory area that is designated to allow the CP to do context save/restore in
mid-wave state.
This patch also modifies the set_queue_properties_from_user() (called from
kfd_ioctl_create_queue()) to check and copy those new parameters.

Because amdkfd will need to work both with radeon and amdgpu, don't include
header files that are in radeon's folder.
Instead, use the common amd include folder and move amdkfd specific defines to
amdkfd header files.
