Sami Kiminki 82ba1277f3 gpu: nvgpu: Limit max CBC clear job size to 16384 lines ...

Limit the maximum job size of CBC ctrl clear to 16 klines. This avoids
timeouts and excessive lock hold duration when clearing comptags for
huge surface. 16 klines corresponds to a 1-GB surface for 64-kB
compression page size.

If the requested CBC ctrl job is larger than 16 klines, split it to
at most 16-kline chunks.
