gpu: nvgpu: ga10b: move grmgr.load_timestamp_prod HAL

Browse Source 
The timestamp control register in the SMCARB should be configured to have
the NV_PSMCARB_TIMESTAMP_CTRL_DISABLE_TICK field cleared, otherwise the PTIMER
ticks will not be sent to GR engine.  Hence, remove the pre-processor checks
around grmgr.load_timestamp_prod call.
