video: tegra: host: nvdla: Align max buffers per task limit

Browse Source 
- Max buffers per task limit was reduced to 384 recently as
  per all usecases from UMD
- Rename the macro to MAX_NVDLA_BUFFERS_PER_TASK to avoid
  conflict with another macro defined in nvdla_inf.h
- Reflect this change in uapi
