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.
to avoid the conflict with 3rd party c++ library(e.g. protobuf):

include/nuttx/clock.h:
* 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().
Select debug.h which may be under include/arch or include/arch/chip.
