Remove an SGL reference from the mm_gk20a.c code. This code is
common code and as such all linuxisms need to be fixed. It just
so happens that this particular function is only used by the
CDE code which is only present in Linux. So simply move this
function over to the CDE code.

Allow userspace to control directly the PTE kind for the mappings by
supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX.
In particular, in this mode, the userspace will tell the kernel
whether the kind is compressible, and if so, what is the
incompressible fallback kind. By supplying only the compressible kind,
the userspace can require that the map kind will not be demoted to the
incompressible fallback kind in case of comptag allocation failure.
Add also a GPU characteristics flag
NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct
kind control is supported.
Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

CDE is only used in Linux platforms, and the code is highly dependent
on Linux APIs. Move the common CDE code to Linux module and leave only
the chip specific parts to HAL.
