Fix: Some STM32 chips don't support GTIM_CCER_CC1NP; use HAVE_GTIM_CCXNP guards to exclude it. Adds/updates #ifdef HAVE_GTIM_CCXNP guards so GTIM_CCER_CC1NP is only included when supported, preventing register writes on chips without it.

Modify ARM64 architecture configuration to disable fork support in protected
build mode (BUILD_PROTECTED). Update ARCH_HAVE_FORK condition from
"!BUILD_KERNEL" to "!BUILD_KERNEL && !BUILD_PROTECTED", ensuring fork is
only available in flat/monolithic builds, not in protected kernel builds.

After addrenv_switch(), the current running task (this_task) may change due to
deferred work execution. Update all architecture interrupt, syscall, and exit
handlers to re-fetch tcb = this_task() after addrenv_switch(). Ensures scheduler
and context operations use the correct TCB, preventing context corruption and
exceptions across SMP and memory-protected builds.

Add REG_SCTLR_EL1 system register initialization in arm64_init_signal_process
when setting up register context for signal handlers. Initialize with current
sctlr_el1 value and apply CONFIG_ARM64_MTE settings if enabled. Fixes regression
where signal handler context was missing critical system control register setup.

Replace direct labels for CPU startup routines with indirection through global
variables. Export cpu1_start, cpu2_start, cpu3_start as global objects containing
addresses to __cpu1_start, __cpu2_start, __cpu3_start respectively. Use load-then-
branch-exchange (ldr r1, =cpu*_start; ldr r1, [r1]; bxeq r1) instead of direct beq
jumps. Enables flexible control of CPU startup positions and supports future AMP/
dynamic loading scenarios.

Add new CONFIG_NCPUS configuration option to support both SMP and AMP modes.
Replace SMP-specific CONFIG_SMP_NCPUS checks with generic CONFIG_NCPUS in ARM
boot code (ARMv7-A, ARMv7-R, ARMv8-R). CONFIG_NCPUS defaults to SMP_NCPUS when
SMP is enabled, or 1 otherwise, enabling multi-CPU support regardless of SMP mode.

Enable SGI (Software Generated Interrupts) usage in AMP mode for inter-core
communication. Modify arm_cpu_sgi() to use SGI_TGTFILTER_LIST for both SMP and
AMP modes instead of requiring CONFIG_SMP. Add CPU0-only guard checks using
sched_getcpu() to ensure arm_gic0_initialize() executes only once on CPU0 during
initialization in both SMP and AMP configurations.

We need IFF_IS_RUNNING(dev->d_flags) to be true for ethernet device to
work properly. However, dev->d_flags are not set anywhere in the
Kinetis' ethernet code.
This change updates kinetis_ifup and kinetis_ifdown procedures to call
netdev_carrier_on and netdev_carrier_off to set dev->d_flags.

Use regs[REG_SP_EL0] from register context instead of direct sp_el0 system
register read/write operations in arm64_syscall(). Replace read_sysreg(sp_el0)
with regs[REG_SP_EL0] and write_sysreg(usp, sp_el0) with direct assignment to
regs[REG_SP_EL0]. Ensures userspace stack pointer is correctly maintained from
register context during signal delivery, preventing userspace SP corruption on
syscall return.

Convert g_mpu_region from single-CPU global variable to per-CPU array indexed
by this_cpu(). Change declaration from "unsigned int g_mpu_region" to
"unsigned int g_mpu_region[CONFIG_SMP_NCPUS]". Update all accesses in
mpu_allocregion(), mpu_freeregion(), and mpu_modify_region() to use
g_mpu_region[this_cpu()] for proper per-CPU MPU region tracking in multi-core

when we build with greenhills compiler, if the exception_common function
is put into a separate section: ".text.exception_common", then the
address of exception_common function is an even number, for example "0x16a6c",
in this case, it will trigger the UsageFaults:INVSTATE error.
The reason for this error is that in the GHS compiler, a section declared
through the ".section" directive must specify at least the "a" attribute.
Otherwise, this section will not be linked into the final file, and this
is why the address of exception_common function is invalid.
The following is the official explanation in the GHS compiler documentation:
"The reason for this error is that in the GHS compiler, a section
declared through the .section directive must specify at least the "a"
attribute. Otherwise, this section will not be linked into the final
file. The following is the official explanation in the documentation:
"Sections that are intended be part of the final linked output should
have at least the `a` attribute"
and for GHS compiler, the .text section is recommended specify the
attribute of `ax`.

The wdog callbacks are executed in the host's signal handler context, which has strict limitations on what operations can be safely performed. Specifically, signal handlers should not call non-async-signal-safe functions (e.g., sim_alsa use mutex_lock in wdog and cause deadlock).
This change only replaces uses of wdog for periodic tasks. Other interrupt callbacks that are still invoked from the host signal handler are not replace to work queue.
