nxsig_timeout calls nxsched_add_readytorun and up_switch_context, so
must be in critical section.
nxsig_timeout is used as wdentry in nxsig_clockwait
See wd_expiration CALL_FUNC is not in critical section.

Move can_bytes2dlc() and can_dlc2bytes() to a common CAN file
that can be shared between socketCAN implementation and CAN
character driver.
This is the first step to simplifying the logic repeated in

Remove dependency on CONFIG_NET_CAN for socketCAN definitions.
Definitions from this file are also used by arch/sim CAN
implementation, which is based on a host socketCAN interface.
With this change CONFIG_NET and CONFIG_NET_CAN don't need to
be enabled to support CAN character driver on sim.

Add a kernel build with OP-TEE/SMC driver enabled to
i.MX93 EVK (target imx93-evk:koptee). Since this is
derived from the 'knsh' target, it is also preconfigured
for use with AHAB boot (see
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html).

So far the NuttX implementation of OP-TEE has been using
registered memory references to pass non-registered memory
to OP-TEE OS, passing the physical address of the memory
in what is normally used as a 'cookie'. This was compatible
with the Openvela framework, but no other OP-TEE OS.
Fix this by passing temporary memory instead with the standard
non-contiguous (OPTEE_MSG_ATTR_NONCONTIG) flag.

This is mostly to handle the case that the user calls
close() before calling close() on the shm. In that case
optee_close() frees the shm and then optee_shm_close()
operates on an invalid reference. Fix that.

This is no longer (exactly) the linked list entry that it
used to be, but rather an associated pointer in an idr tree
entry. Plain 'optee_shm' is more concise, and more appropriate.
Changes also reg_pair_to_uintptr() to reg_pair_to_ptr() for
better readability in invocations.

Previous implementation was not compatible with GlobalPlatform
API in the following ways:
- Registered mem IDs would begin from negatives when it should
have been greater than or equal to 0
- Register IOCTL would return 0 on success, when it should have
been returning a file descriptor.
- Register IOCTL would expect the user-space client to specify
TEE_SHM_* flags dictating its behaviour when in fact, libteec
never specifies flags.
This commit fixes all those issues. It uses nuttx/idr.h instead
of a linked list, and it uses `file_allocate` to provide file
descriptors for registered shared memory. Upon close(fd), the
memory is de-registered and freed accordingly. It also updates
the documentation accordingly.

This commit resolves a timing error caused by the round-up behavior in clock_time2ticks. In rare cases, this could lead to a two-tick increment within a single tick interval. To fix this, we introduced clock_time2ticks_floor, which guarantees the correct semantics for obtaining current system ticks.

This commit added CONFIG_TIMER_ADJUST_USEC to support the time compensation for wdog timer. Normally, timer event cannot triggered on exact time due to the existence of interrupt latency. Assuming that the interrupt latency is distributed within [Best-Case Execution Time, Worst-Case Excution Time], we can set the timer adjustment value to the BCET to reduce the latency.
