gpu: nvgpu: Add load_timestamp_prod in grmgr init

Browse Source 
1) Moved load_timestamp_prod handling in nvgpu_init_gr_manager().
2) Moved fifo.reset_enable_hw in nvgpu_early_init() -
   In simulation/emulation/GPU standalone platform,
   XBAR, L2 and HUB are enabled during g->ops.fifo.reset_enable_hw().
   This introduces a dependency to get the MIG map conf information.
   (if nvgpu_is_bpmp_running() == false treated as
   simulation/emulation/GPU standalone platform).
