gpu: nvgpu: split sema sync hal to wait and incr

Browse Source 
Instead of one HAL op with a boolean flag to decide whether to do one
thing or another entirely different thing, use two separate HAL ops for
filling priv cmd bufs with semaphore wait and semaphore increment
commands. It's already two ops for syncpoints, and explicit commands are
more readable than boolean flags.

Change offset into cmdbuf in sem wait HAL to be relative to the cmdbuf,
so the HAL adds the cmdbuf internal offset to it.

While at it, modify the syncpoint cmdbuf HAL ops' prototypes to be
consistent.
