Antony Clince Alex 95bfa039f5 gpu: nvgpu: tu104: implement l2 sector promotion
Introduce new HAL gops_ltc.set_l2_sector_promotion to configure L2
sector promotion policy. The follow three promotion settings are support:
- NVGPU_GPU_IOCTL_TSG_L2_SECTOR_PROMOTE_FLAG_NONE
- NVGPU_GPU_IOCTL_TSG_L2_SECTOR_PROMOTE_FLAG_64B
- NVGPU_GPU_IOCTL_TSG_L2_SECTOR_PROMOTE_FLAG_128B

Add ioctl "NVGPU_TSG_IOCTL_SET_L2_SECTOR_PROMOTION" to the gpu tsg node
to support l2 sector promotion. On chips which do not support sector
promotion, the ioctl returns 0.
