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

Instead of relying on kernel version to determine if functions or
specific versions of functions are present in the kernel, add compile
time tests 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.

CONFIG_CAN_LEDS has been marked as BROKEN since Linux v4.19 and was
finally removed in Linux v5.19. Only compile support for LEDS if enabled
in the kernel. Long-term we need to move the MTTCAN driver to use
LEDS_TRIGGER_NETDEV.
This is a better solution for working with 3rd party Linux kernels that
may backport upstream changes to the kernel and hence are not compatible
with these existing version checks.

ether_get_tx_ts, pdata->tx_ts_ref_cnt is an atomic variable
that is used as a mutex in this function and should not return 0
if the function fails to acquire the mutex.
The workqueue is scheduled when the return value of the
judgment function is <0. If one CPU core execution softirq
is running in ether_get_tx_ts function and another CPU core
softirq also calls ether_get_tx_ts function to get hardware
timestamp, then the acquisition of mutex fails and return 0.
After returning 0, the workqueue is not scheduled.
The timestamp cannot be obtained in time. So ether_get_tx_ts
should returns -1 on failure to acquire the mutex.
