gpu: nvgpu: construct initial utf for sync unit.

This patch constructs the initial setup for sync unit.
There are three simple tests currently. The first test inits the
environment necessary such as regspace init, hal init. The second
step simply fails the creation of the sync and the last test is meant
as a deinit step.
