682abd7b5c nvgpu: fix multiple build issues for QNX 
- timers and bug header files should be
  included directly. Linux maybe getting
  it via indirect includes. Also, QNX
  requires non-static function to be
  declared explicitly.

49dc335cfe gpu: nvgpu: fix pmu state change for dgpu boot 
In pmu_handle_pg_elpg_msg, when processing ELPG_MSG_DISALLOW_ACK, if current
pmu state is ELPG_BOOTING and GR_POWER_GATING is not supported, make sure
nvgpu_pmu_state_change updates the state_change flag, since PMU is now fully
initialized. In particular, this fixes PMU boot for dgpu, which does not support
GR_POWER_GATING.

2e07e06330 gpu: nvgpu: Remove unnecessary use of ACCESS_ONCE() 
ACCESS_ONCE() is used for making sure that in a given place of code
access a variable exactly once. It prevents compiler rearranging the
read from happening earlier.

Remove its use from cases where rearranging of the read does not
create problems.
