Summary:
- This commit introduces SP_WFE() and SP_SEV() to be used for spinlock
- Also, use wfe/sev instructions for ARMV7-A to reduce power consumption
Impact:
- ARMV7-a SMP only
Testing:
- sabre-6quad:smp (QEMU, dev board)
- maix-bit:smp, esp32-devkitc:smp, spresense:smp sim:smp (compile only)

Right now, same as printflike.
Introduce a separate macro because syslog takes
a bit different format from printf. (ie. %m)
If it turns out that a compiler is not happy with
the difference, we can disable this selectively.
Summary:
- This patch change the data type of buflen in qspi_meminfo_s
- from uint16_t to uint32_t to allow data size greater than 64KB.
Impact:
- QSPI & some flash like s25fl1 etc
Testing:
- Tested with rm69330 oled controller on custom board

* USEC_PER_TICK: The docstring for this define mistakenly said
that the default value of USEC_PER_TICK, 10000, corresponded
to 100 KHz. However, it is actually 100 Hz. Corrected the
comment. No functional changes.
sched/signal/sig_timedwait.c:
* nxsig_timedwait(): Fix typo in comment:
"is store din" -> "is stored in"
include/nuttx/signal.h:
* Fix same typo in extern declaration of nxsig_timedwait().

Follow the POSIX description.
SIGTSTP should be sent when the Ctrl-Z characters is encountered, not SIGSTP.
Testing:
Built with hifive1-revb:nsh (CONFIG_SERIAL_TERMIOS=y, CONFIG_SIG_DEFAULT=y and CONFIG_TTY_SIGTSTP=y)
Correct typo LCD_SSD1306_SPI to CONFIG_LCD_SSD1306_SPI, remove
references to non-existent config variable names in comments.
