drm/amdgpu: update the functions to use amdgpu version of hmm

Browse Source 
At times we need a bo reference for hmm and for that add
a new struct amdgpu_hmm_range which will hold an optional
bo member and hmm_range.

Use amdgpu_hmm_range instead of hmm_range and let the bo
as an optional argument for the caller if they want to
the bo reference to be taken or they want to handle that
explicitly.
