Dinesh T b05341134b gpu: nvgpu: Read device tree to get the supported syncpoints ...

The patch is adding a OS specific call to get the supported
syncpoints from the DT entry. The syncpoints is used to
initialize the number of supported channels while GPU
initialization.

The error path is taken care with the default value 256.

As device tree entries not available in upstream, the path
handled with the default value 256.
