- ZBC save/restore registers are removed in GP10B PMU ucode.
- These registers are saved/restored from CTXSW ucode during

- Accessing the ZBC registers will cause PMU EXTERR error.
- To resolve this, ZBC functionality is removed from GP10B
feature list in PMU ucode.
- From NvGPU driver, set NVGPU_PMU_ZBC_SAVE bit to false
for GP10B
