Based on the Mbed OS website the A3 is connected to "DAC", however there
is no define for DAC. In order to get the Realtek RTL8195AM to even compile
with mbed-os-example-client now, we must have the A3 defined - it is one of
the standard Arduine header pins. Therefore, setting it as NC.
A4-A5 are not connected either, so adding them as "NC" as well.
Realtek will hopefully push a proper fix sooner or later, if there is a
more meaningful define for the A3 pin. They do state however that the
A0-A3 pins are not GPIO capable anyway.

Add a note to each CAS making explicit that the functions are strong.
Minor wording change to expectedCurrentValue - use of "still updated"
about the failure case suggested that it might be written to on success.
For some uses it's critically important that expectedCurrentValue only
be written on failure, so change wording to "instead updated".
The LDREX/STREX implementations of the compare-and-swap functions were
weak (they could spuriously fail when the value was expected), whereas
the critial section implementation was strong, and the documentation has
no suggestion that there might be spurious failures.
Rationalise by adding a retry loop for STREX failure, so that it only
returns false when the value is not expected.

GattServer::write on Nordic's targets use sd_ble_gatts_hvx to send an
handle value Notification or Indication; This function can fail if the
connection handle is invalid or if Updates are not enabled for this
connection.
This patch workaround those limitations.
Timer code was written based on integer multiple HF clock frequencies. EFR32 doesn't conform to that (38.4), and so the timestamp ticks were off by 1%. Enough to trip up some CI tests on TB_SENSE_12 (#5496)
armcc fopen allocated a mutex using the retargeted system-level
_mutex_initialize function. Interestingly, malloc also uses this
same _mutex_initialization function, which prevents a full solution
relying on malloc. The solution previously implemented involved using
the rtx mutex pool for the first 8 mutexes, then falling back on
malloc.
The previous implementation relied on osMutexNew returning an error
on out-of-memory. An unrelated change causes osMutexNew to instead
assert (except for release mode). This meant if you exceed 8 system-
level mutexes in armcc you will hit an assert. Since the filesystem
code can call fopen an unlimited number of times, this is a problem.
Solution is to keep track of which static mutexes we've allocated, so
we know before calling osMutexNew if we need to call malloc.
Also _mutex_free never deallocated the malloced mutexes, which would
cause fopen to leak memory.
