gpu: nvgpu: fix priv error register reads
Current code does not compute priv error register offsets
properly. This leads to invalid decoding of priv errors, and
can also trigger additional priv errors.
- add GPU_LIT_GPC_PRIV_STRIDE define
- return proj_gpc_priv_stride for GPU_LIT_GPC_PRIV_STRIDE in hals
- use GPU_LIT_GPC_PRIV_STRIDE instead of GPU_LIT_GPC_STRIDE in
g->ops.priv_ring.isr() to compute priv error register offsets.
