I think this was an abstraction back from when
kfd supported both radeon and amdgpu. Since we just
support amdgpu now, there is no more need for this and
we can use the amdgpu structures directly.
This also avoids having the kfd_cu_info structures on
the stack when inlining which can blow up the stack.

If new range is splited to multiple pranges with max_svm_range_pages
alignment and added to update_list, svm validate and map should keep
going after error to make sure prange->mapped_to_gpu flag is up to date
for the whole range.
svm validate and map update set prange->mapped_to_gpu after mapping to
GPUs successfully, otherwise clear prange->mapped_to_gpu flag (for
update mapping case) instead of setting error flag, we can remove
the redundant error flag to simpliy code.
Refactor to remove goto and update prange->mapped_to_gpu flag inside
svm_range_lock, to guarant we always evict queues or unmap from GPUs if
there are invalid ranges.
After svm validate and map return error -EAGIN, the caller retry will
update the mapping for the whole range again.

There are cases where HSA runtime is not enabled through the
AMDKFD_IOC_RUNTIME_ENABLE call when adding queues and the MES ADD_QUEUE
API should clear the MES process context instead of SET_SHADER_DEBUGGER.
Such examples are legacy HSA runtime builds that do not support the
current exception handling and running KFD tests.
The only time ADD_QUEUE.skip_process_ctx_clear is required is for
debugger use cases where a debugged process is always runtime enabled
when adding a queue.

The NULL initialization of the pointers assigned by kzalloc() first is
not necessary, because if the kzalloc() failed, the pointers will be
assigned NULL, otherwise it works as usual. so remove it.

To prevent its redundant implementation and streamline
code, use memdup_user.
This fixes warnings reported by Coccinelle:

When CONFIG_DYNAMIC_DEBUG is disabled altogether, calling
_dynamic_func_call_no_desc() does not work:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c: In function 'svm_range_set_attr':
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:52:9: error: implicit declaration of function '_dynamic_func_call_no_desc' [-Werror=implicit-function-declaration]
52 | _dynamic_func_call_no_desc("svm_range_dump", svm_range_debug_dump, svms)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:3564:9: note: in expansion of macro 'dynamic_svm_range_dump'
3564 | dynamic_svm_range_dump(svms);
| ^~~~~~~~~~~~~~~~~~~~~~
Add a compile-time conditional in addition to the runtime check.
