gpu: nvgpu: add max_css_buffer_size characteristic
Add max_css_buffer_size to gpu characteristics. In the virtual
case, the size of the cycle stats snapshot buffer is constrained
by the size of the mempool shared between the guest OS and the
RM server, so tools need to find out what is the maximum size
allowed.
In the native case, we return 0xffffffff to indicate
that the buffer size is unbounded (subject to memory availability),
in the virtual case we return the size of the mempool.
Also collapse native init_cyclestats functions to a single version,
as each chip had identical versions of the code.
