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.

To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute
on different hardware resources.
This feature requires a change in software to make it possible
to modify the virtual SM id to TPC mapping across mission and
redundant contexts.
This CL adds only SM diversity flags which are exposed to
its clients through ioctl/devctl interfaces.
Actual virtual SM id to TPC mapping implementation
will be part of upcoming patch sets.
