video: tegra: gk20a: Disable gfx before save zbc
This change disables gr engine before calling into pmu
for saving zbc and re-enables once it is finished.
Looks like NV_PPWR_PMU_BAR0_FECS_ERROR_CODE_PRI_TIMEOUT
error during access of NV_PLTCG_LTCS_LTSS_DSTG_ZBC_COLOR_CLEAR_VALUE
happens because of active concurrent memory traffic.
