d6359b5adc gpu: nvgpu: specify devfreq timer through dt 
Originally,
nvgpu uses deferrable timer for devfreq polling by default,
this leads to issues below because of unstable polling interval.
 - out of time frequency scaling
 - unstable GPU frequency scaling

This change lets users be able to specify devfreq timer through dt.
If the dt node 'devfreq-timer' equals to 'delayed', then gpu will uses
delayed timer for devfreq polling.

878182c1d5 gpu: nvgpu: disable nvgpu rpm if genpd support is not available 
GPU is set to always ON state on safety L4T for SMCU to not fault.
However, nvgpu railgating was always enabled. This will lead to
improper GPU railgate/unrailgate sequence as bpmp will not
powergate/ungate the gpu on suspend and resume requests.

Keeping rpm enabled can lead to ACR failure on resume as it expects
the GPU to be reset on every resume.

Disable nvgpu runtime PM when the power domain node for the gpu is
not defined.

bd5ab81ccc gpu: nvgpu: nvs: queue direction update 
Changes:
-  update nvgpu_nvs_ctrl_queue to have queue direction as it is required
by gsp scheduler to erase queue individually
- queue direction is updated during ioctl call to create queue and is
used only by gsp scheduler. So no other moduler should be affected by
it.

- need to pass the size of struct which is u32 so downgrading it from
u64 to u32 is intentional, misra C violation 10.3 can be ignored here

- During nvgpu_poweron, PERFMON_INIT RPC and
  ACR_INIT_WPR_REGION command is sent to PMU in two different threads.
- For perfmon RPC method is used and for ACR, CMD-MSG queue is used.
- Since the pmu thread and poweron thread run in parallel, the
  pmu sequence acquired by both can have the same seq_id.
- For Perfmon RPC, nvgpu_pmu_seq_free_release() is called
  followed by nvgpu_pmu_seq_release().
- This causes clearing of sequence for the next command.
- To resolve this, instead of nvgpu_pmu_seq_free_release(),
  just free the rpc-payload after getting ack for perfmon and
  then do sequence release.
- This ensures that the ACR cmd sent just after perfmon RPC does
  not get the same seq_id and the sequence is not cleared.
