important information, so let's standardize this interface.

an ELF application
- This commit fixes this issue by re-mapping the address
to SYSBUS in up_module_text_free()

If the subcore configuration, which is mainly used in the Spresense
Arduino environment, is enabled, the serial console has been already
initialized by maincore. Then, don't need to re-initialize the UART1
serial driver.
ADC driver does not support multiple open and close. It causes the memory
corruption by multiple free. This commit fixes this problem by introducing
the reference counter.
If the system clock is changed during loading gnssfw, gnss open may be
failed. So this commit prohibits clock change until loading gnssfw is
completed.
There is an issue that the next alarm is expired immediately after
canceling a RTC alarm. Fixed alarm settings to be completely cleared
when canceling an RTC alarm.
If the system clock is changed during the SPI transfer, the SPI data can
be corrupted. So this commit prohibits the clock change during SPI transfer,
and keep the clock until the transfer is completed.
Introduce PM_CPUFREQLOCK_FLAG_HOLD into the frequency lock mechanism in
power manager, which is used to keep the current frequency without clock
change, for example, during the transfer of a periphral.
UART driver is stopped and re-started during a clock change. When a UART
interrupt is generated in each process, the unexpected behavior will
occur and a console will get stuck with UART driver. This commit fixed
each process is performed atomically.
Currently Nuttx doesn't seem to be any real support for OTG.
In the future when OTG is supported. This Knob can be removed
and drivers can enable their pin sets based on CONFIG_OTG.
(Adding CONFIG_OTG at this time would be misleading.)

Summary:
- This commit adds stack coloration for the idle task

Summary:
- The NuttX for raspberrypi-pico boots via the boot_stage2 provided
by the pico-sdk which sets the MSP at the end of the SRAM.
- However, the NuttX expects the MSP is set to the top of the idle stack.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with nsh, nshsram and smp configrations
Summary:
- SP_SECTION was introduced to allocate spinlock in non-cachable
region mainly for Cortex-A to stabilize the NuttX SMP kernel
- However, all spinlocks are now allocated in cachable area and
works without any problems
- So SP_SECTION should be removed to simplify the kernel code

Change the logic for allocating user heap for PROTECTED_BUILD:
- Don't rely on SRAM1_END alignment
- Make better use of MPU subregions when allocating the heap

All supported arch uses a push-down stack:
The stack grows toward lower addresses in memory. The stack pointer
register points to the lowest, valid working address (the "top" of
the stack). Items on the stack are referenced as positive(include zero)
word offsets from sp.
Which means that for stack in the [begin, begin + size):
1.The initial SP point to begin + size
2.push equals sub and then store
3.pop equals load and then add

That field is never used and, in most cases, is never initialized correctly.
This should have no impact to anything with the possible exception of free-running drivers.
Verified using CI builds only.
The comments at the top of the file say this:
```
This will be automatically registered
* - AXI SRAM is a 512kb memory area. This will be automatically registered
* with the system heap in up_allocate_heap, all the other memory
* regions will be registered in arm_addregion().
```
but the implementation was using SRAM123 instead. Furthermore, arm_addregion then re-adds SRAM123 again.
