Instead of relying on kernel version to determine if the 'dev' member of
the 'struct class' is const, add a compile time test to the conftest.sh
script to determine this at compile time for the kernel being used. This
is beneficial for working with 3rd party Linux kernels that may have
back-ported upstream changes into their kernel and so the kernel version
checks do not work.

The MODULE_IMPORT_NS macro adds a namespace tag to the module
information. The DMA_BUF namespace is required for Linux v5.16+ kernels
for drivers that use DMA BUF, there is no reason not to populate this
for earlier kernels. Furthermore, some 3rd party kernels prior to v5.16
may require this too and so drop the version check around the DMA BUF
namespace.
The MODULE_IMPORT_NS macro was introduced in Linux v5.4 and so if the
kernel defines this, then add the DMA_BUF namespace.

Determining whether the header file iosys-map.h is present in the kernel
is currently determine by kernel version. However, for Linux v5.15,
iosys-map.h has been backported in order to support simple-framebuffer
for early display. Therefore, we cannot rely on the kernel version to
indicate whether iosys-map is present. This is also true for 3rd party
Linux kernels that backport changes as well. Fix this by adding a
compile time flag, that will be set accordingly by the conftest script
if this header is present.

The soft-depedenency for the governor_pod_scaling_v2 driver was
initially added to ensure this driver is loaded when built as an
out-of-tree module. The driver has now been renamed to
governor_pod_scaling but instead of simply updating the soft-dependency
name a new soft-dependency was added specifically with the new driver
name. This is not necessary and this also breaks frequency scaling
support for kernels for kernel to prior to v5.15. Fix this by removing
this compile time check and legacy soft-dependency.

When building NVGPU with virtualization enabled, we need to ensure that
the ccflag CONFIG_TEGRA_VIRTUALIZATION is defined. The Tegra HV driver
is only compiled when CONFIG_TEGRA_VIRTUALIZATION is defined. When NVGPU
is compiled without defining CONFIG_TEGRA_VIRTUALIZATION, then function
stubs in the header file "soc/tegra/virt/hv-ivc.h" will be used and these
stubs will return an error when called causing virtualization to fail.

This is implementation used when the userd.gp_get() is not defined and
also the feature flag NVGPU_SUPPORT_SEMA_BASED_GPFIFO_GET is set.
At the end of each job submitted, submit a semaphore to write the
gpfifo get pointer at hw semaphore addr. At next job submission
processing we will read the gpfifo.get from the designated hw semaphore
location.

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.

- 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
