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.

- 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

specification wherein dma-buf reservation is to be locked while
accessing the dmabuf internal data. Lock is removed. So lock
the resv object onwards while updating dmabuf private data

With this, we can enable compression for all kernel versions that
was disabled earlier for v6.2+ kernels.

a5640d61bd gpu: nvgpu: free VEID if the channel is closed 
In case of process crash or forceful closure of the channels, userspace
may not release the VEID. In that case, creating further subcontexts
may not be possible.

Hence, when the channel is closed forcibly (linux), release the VEID on
closure of the last channel in the subcontext.

With this, normally on linux, channel close will not relase the VEID
However, on qnx it will release the VEID. So delete subcontext devctl
call on qnx will be nop in normal case hence changed the error print
and error return to success.

Also added check in the subcontext delete ioctl fn that all channels
are unbound before deleting the subcontext. This is to ensure that
channels don't refer to dangling subcontext pointer.

03533066aa gpu: nvgpu: Disable compression for k6.1+ 
dmabuf internals that nvgpu relies upon for storing meta-data for
compressible buffers changed in k6.1. For now, disable compression
on all k6.1+ kernels.

Additionally, fix numerous compilation issues due to the bit rotted
compression config. All normal Tegra products support compression
and thus have this config enabled. Over the last several years
compression dependent code crept in that wasn't protected under the
compression config.
