Summary:
- In cxd56xx, ldrex/strex behavior is slightly different from
other Arm architectures. Dummy strex must be issued to release
the exclusive load & store unit.
Impact:
- SMP only
Testing:
- Tested with spresense:smp
- Tested with spresese:wifi_smp, spresense:rndis_smp
- NOTE: CONFIG_CXD56_TESTSET=y must be removed from defconfigs

Drop to user-space in kernel/protected build with up_pthread_exit,
now all pthread_cleanup functions executed in user mode.
* A new syscall SYS_pthread_exit added
* A new tcb flag TCB_FLAG_CANCEL_DOING added
* up_pthread_exit implemented for riscv/arm arch

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.
