user mode will still use pte ring as a normal ring.
if the prepare job generates another command(update pte) on its ring in scheduler,
then will kill scheduler which is going to waiting later job but pending running job.

The comment is misleading and incorrect, remove it.

CGS (Common Graphics Services) is an AMD cross component
abstraction layer to designed to better encapsulate
specific IP block drivers so different teams can effectively
work on differnet IP block drivers independently. It provides
a common interface for things like accessing registers,
allocating GPU memory, and registering interrupt sources.
The plan is to eventually move more and more IP drivers to
this interface. The first user is the ACP IP driver.

This patch adds an interface file between amdgpu and amdkfd. This
interface file is H/W agnostic, thus containing functions that
operate the same for any AMD APU/GPU H/W generation.
The functions in this interface mirror (some) of the functions in
radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
are:
- amdgpu_amdkfd_init - initialize the amdkfd module
- amdgpu_amdkfd_load_interface - load the H/W interface according to the
currently probed device
- amdgpu_amdkfd_device_probe - probe the device in amdkfd
- amdgpu_amdkfd_device_init - initialize the device in amdkfd
- amdgpu_amdkfd_interrupt - call the ISR of amdkfd
- amdgpu_amdkfd_suspend - suspend callback from amdgpu
- amdgpu_amdkfd_resume - resume callback from amdgpu
This patch also modifies the relevant amdgpu files, to use this new
interface.
