gpu: nvgpu: Add check_priv_security fuse ops

-New fuse ops is added to set NVGPU_SEC_PRIVSECURITY
 and NVGPU_SEC_SECUREGPCCS bits in g->enabled_flags
 during hal initialization

-For igpu non simulation platforms, fuses are read
 to decide if gpu should be allowed to boot or not.
--Do not boot gpu if priv_sec_en is set but wpr_enabled
  is not set to 1 or vpr_auto_fetch_disable is not set to 0
--With priv_sec_en set, all falcons have to boot
  in LS mode and this needs wpr_enabled set to 1
  AND vpr_auto_fetch_disable set to 0. In this case
  gmmu tries to pull wpr and vpr settings from tegra mc
