gpu: nvgpu: Remove PTE kind logic

Browse Source 
Since NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL was made mandatory,
kernel does not need to know the details about the PTE kinds
anymore. Thus, we can remove the kind_gk20a.h header and the code
related to kind table setup, as well as simplify buffer mapping code
a bit.
