Debarshi Dutta db80498307 gpu: nvgpu: add CONFIG_NVGPU_KERNEL_MODE_SUBMIT flag
Following are removed for safety build by adding
CONFIG_NVGPU_KERNEL_MODE_SUBMIT flag.

1) HAL ops in g->ops.sync.syncpt

add_wait_cmd
get_wait_cmd_size
add_incr_cmd
get_incr_cmd_size
get_incr_per_release

2) g->ops.sync.sema is removed in its entirety and contains the
following ops.

3) The following files are compiled out using the above flag.
hal/sync/sema_cmdbuf_gk20a.c
hal/sync/sema_cmdbuf_gv11b.c
