The new Tegra Prod APIs are to be used for NVIDIA Linux kernels v5.16+.
Building the MTTCAN and QUAD SPI driver currently fail for upstream
Linux v5.16 because the various version definitions are not correct.
Some definitions have greater than v5.16.0 instead of greater than OR
equal to v5.16.0. This means that the new APIs will only be used
starting with v5.16.1+ and not v5.16.0 as inteaded.
Other definitions have less than or equal to v5.16.0 instead of just
less than v5.16.0. This means that we will still use the legacy APIs for
v5.16.0.
Fix this by correcting the definition that the drivers can be built for
upstream Linux v5.16.

Issue:
The L2 Orin bridge use case is encountered
an issue on AV+L NDAS builds for VLAN ping
from HOST1 to HOST2 over L2 Orin bridge.
As HOST1/HOST2 VLAN packets are dropped
by EQOS/MGBE MAC due to VLAN VID feature enable.
Fix:
To support the L2 Orin bridge VLAN
HOST1 to HOST2 data usecase, disable
the VLAN VID filters in the nvethernet driver.

The flag CONFIG_TEGRA_IVC_LEGACY_DISABLE was added so that it can be set
by an external Makefile that build the out-of-tree drivers. If this flag
is set by an external Makefile then the ccflags definition
'-DCONFIG_TEGRA_IVC_LEGACY_DISABLE' does not get set as expected and
builds fail. Fix this by setting the ccflag if the Make flag
CONFIG_TEGRA_IVC_LEGACY_DISABLE is set and not just for Linux v6.2+
kernels.

In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and
this breaks building some of the out-of-tree drivers for Linux v6.2+
kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks
building some of the out-of-tree drivers that use these legacy APIs. For
now the broken drivers are not built for these corresponding kernels.
Instead of checking the kernel version in the Makefile for the
corresponding broken driver, move the kernel version checking to the
top-level Makefile and add CONFIG definitions that can be used the
various Makefiles.
This is also needed for working with 3rd party Linux kernels that may
have upstream backports and need to set these CONFIG variables for their
Linux kernel.

Consider the following execution scenario, it can lead to a data race
Thread 1 Thread 2
-------------------------------------------------------
NvRmMemHandleAllocAttr
NvRmMemGetFd
NvRmMemHandleFromFd close(fd), NvRmMemHandleFree
When thread 1 is executing NvRmMemHandleFromFd while thread 2 is closing
the fd and freeing the handle, then following sequence will lead to
accessing a freed dma-buf and may lead to dereference issue.
- TH1: Get handle from fd and increment handle's refcount.
- TH2: Close the fd and start execution of NvRmMemHandleFree.
- TH2: Decrement ref's dup count, it will become 0, hence ref would be
freed and dma-buf as well, but as handle's refcount is incremented in
step 1, handle won't be freed.
- TH1: Resume HandleFromFd part, call to nvmap_duplicate_handle. Ref is
already freed, so generate new ref and increment dma-buf's count but as
dma-buf is freed already, accessing dma-buf will lead to dereferene
issue. Hence, we need to add a null check here and return error value in
such scenario.
Also, add check for return value of nvmap_handle_get, at missing places.

Rather than using kernel version checks to determine which kernel APIs
to use, add the necessary tests to the conftest script to determine
which kernel APIs are present in the kernel.
Note that the function snd_soc_dai_init_dma_data() has been present
in the Linux kernel since v3.13 and so use this for all kernel versions.
In Linux v6.3, the 'playback_dma_data' and 'capture_dma_data' members of
the snd_soc_dai_driver structure were replaced and so these could no
longer be set directly. However, the arguments to
snd_soc_dai_init_dma_data() have not changed and so can be used for
older kernels and well has the current.
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.
