gpu: nvgpu: Kill pg init thread if pmu boot fails
- Created nvgpu_kill_task_pg_init() method to set
pmu state to PMU_STATE_EXIT & make thread stop,
and poll to confirm thread stopped.
- Check for PMU/SEC2 ACR secure boot completion
status & initiate pg init thread kill if ACR boot
exits with error, which fails to validate &
boot LS-PMU.
- Set pmu state to PMU_STATE_OFF after thread kill
during ACR boot failure.
Issue: pg init task blocks if PMU boot fails &
cause kernel to show message "task nvgpu_pg_init_g:2120
blocked for more than 120 seconds"
