gpu: host1x: Annotate intentional syncpoint wrap-around

Browse source

Host1x syncpoints are 32-bit counters that roll over by design.
To make that explicit in the code, use wrapping_* functions whenever
arithmetic is done on syncpoint values.

Atomic operations cannot be updated but a comment is added.
