gpu: nvgpu: implement new host semaphore methods for Volta

Semaphore methods currently being used in Volta are deprecated for future chips
And on Volta we support both old and new methods

So replace old methods by new methods on Volta itself so that new methods
get tested on silicon

Implement below HALs for Volta with new semaphore methods
gops.fifo.add_sema_cmd() to insert HOST semaphore acquire/release methods
gops.fifo.get_sema_wait_cmd_size() to get size of acquire command buffer
gops.fifo.get_sema_incr_cmd_size() to get size of release command buffer

Also use new methods in these APIs
gv11b_fifo_add_syncpt_wait_cmd()
gv11b_fifo_add_syncpt_incr_cmd()

And change corresponding APIs to reflect correct size of command buffer
gv11b_fifo_get_syncpt_wait_cmd_size()
gv11b_fifo_get_syncpt_incr_cmd_size()
