gpu: nvgpu: remove ZBC save/restore by PMU
- ZBC save/restore registers are removed in GP10B PMU ucode. - These registers are saved/restored from CTXSW ucode during ELPG entry/exit. - 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 - Updated the GP10B PMU app version for the ucode: https://git-master.nvidia.com/r/c/tegra/kernel-firmware-t18x/+/2476260 P4 CL link related to this PMU ucode change: https://p4sw-swarm.nvidia.com/changes/29594520 Bug 3233071 Bug 200696431 Change-Id: If3f1707b79699e7e2e65367418b25ac71b09cf0b Signed-off-by: Divya Singhatwaria <dsinghatwari@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2476259 Reviewed-by: Mahantesh Kumbar <mkumbar@nvidia.com> Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
