Terje Bergstrom 8e611fb654 gpu: nvgpu: Hard code map_buffer_batch_limit
Add a hard coded #define for map_buffer_batch_limit and use that
insted of querying from GPU characteristics. Also add an
nvgpu_is_enabled() flag for disabling batch mapping, and set
map_buffer_batch_limit to zero if batch mapping is disabled.
