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.

Need 16KB per task to hold l1table.
Also critical_section no longer required, as table per-task maintained.
For complex goldfish emulator scarios can speed up:

to 01.501500/00:06.587300
at least 10 times faster.

Add timestamp for GNSS measurements and clock, for matching.
When recovering the combination of `GnssMeasurement` and `GnssClock` into
[GnssData](https://android.googlesource.com/platform/hardware/libhardware/+/
refs/heads/android14-release/include/hardware/gps.h#1748),
the reason for splitting is that the uORB buffer is not large enough to
accommodate `GnssData`, since different topics cannot guarantee the
same timing when publishing and subscribing data, we need an index to match.
WARNING: A new member "timestamp" of type uint64_t has been added at
the beginning of the struct "sensor_gnss_measurement" and "sensor_gnss_clock".

This commit fixed work_cancel_sync at a very rare boundary case. When a worker thread re-enqueues the work data structure during the execution of work, the user thread cannot directly dequeue the work in work_cancel_sync. Instead, it should wait until all workers' references to the work data structure have been eliminated after dequeuing.

MMU initialization is redundant for bootloaders(BL2) that load TF‑A(BL31).
TF-A will ignore and overwrite any MMU configuration performed by BL2.
Additionally the MMU comes with a large memory footprint (~50 KB)
which could be precious for such setups.
When the MMU is disabled all the memory is treated as device memory and
all alignment faults generate exceptions (as opposed to normal memory when
MMU is enabled). For that reason we need to add -fno-builtin when compiling
with CONFIG_ARCH_USE_MMU != y to prevent alignment faults.
- Guard MMU initialization with CONFIG_ARCH_USE_MMU
- If CONFIG_ARCH_USE_MMU is not set add -fno-builtin which prevents alignment errors.
- Deliberately didn't try to replace CONFIG_ARCH_HAVE_MMU with CONFIG_ARCH_USE_MMU
occurrences, because this will break a lot of build targets that assume MMU without
guarding the MMU initialization.

This adds support for the i.MX9 ROMAPI, allowing boot in a more
device agnostic and portable manner. The ROMAPI "natively" allows to:
- Query the boot device for information.
- Copy data from the boot device to RAM.
An extra functionality was added to ROMAPI to calculate
offsets of sequential AHAB containers.
The AHAB functionality is built on top of raw ELE primitives and allows to:
- Authenticate a container image.
- Release the authenticated container.

So far NuttX has supported OP-TEE interfacing over
local and RPMsg sockets. This commit introduces support
for direct invocation of OP-TEE through arm SMCs. The
SMC transport is enabled through CONFIG_DEV_OPTEE_SMC.
This SMC implementation has been tested only with arm64,
OP-TEE rev 4.4.
Note that it does not support reverse direction RPCs,
i.e. from the Secure World to the Normal World to
something like optee supplicant. A basic RPC handling
skeleton is provided with implementation for some
basic functions (alloc/free mem, and foreign interrupts)
but no supplicant command handling.

to satisfy the spellchecker during PR)

Adds support for SHM_REGISTER IOCTL. Registration can
be requested both against the driver (for automatic cleanup)
and against the secure OS (for sharing).
Introduces also `optee_{msg,free}_alloc()` to allocate
aligned memory for message arguments depending on the
`alignment` specified in the driver's private data. For
alignment greater than word size, memory is allocated on the
heap, otherwise it's allocated on the stack (similar to the
previous implementation but using `alloca()` instead).

When using pthread_kill, the signal should be delivered to the
specified thread. Current implementation, however, may add the
signal to the groups pending list, if the signal is masked at the
time of dispatch. From the group's pending list it can be delivered
to any thread of the group, which is wrong.
Fix this by adding a new field "FAR struct tcb_s *tcb" to
"struct sigpendq", marking if the signal needs to be delivered
to a specific thread. Use NULL for the value if delivery to any
thread in the group is ok.
