At 9600 baud, a large part of the serial output of the crash reporting
example is missing on CI boards, causing the example test to fail. At
a higher serial speed (115200 baud), the entire output is intact.
This is in alignment with ARMmbed/mbed-os-example-crash-reporting#65.
Fixes#14535
Runtime code that analysed clock frequency to determine numerator and
denominator for conversion to standard 1MHz failed to handle the case
of either being 1 correctly.
Although it would spot other values that could be performed as shifts,
it failed to spot that 1 is "shift by 0", so would end up doing runtime
multiply and/or divide by 1. The runtime divide by 1 could be slow on a
Cortex-M0 device, increasing interrupt latency.
UART character loss on STM32F0 devices has been traced to this incorrect
code.
Correct the `exact_log2` routine so that `exact_log2(1)` returns 0 to
fix this.
Original code had a single special no-multiply-or-divide case for
hardware clock frequency being exactly 1MHz, as USTICKER is on STM32F0 -
this code lacks that but has a more general special case that covers all
shift-convertible frequencies like 500kHz or 8MHz, which should be
similar speed as shifts are cheap.
The repository mbed-os-example-nfc contains two examples: NFC_EEPROM
and NFC_SmartPoster. According to their respective `mbed_app.json`,
only NUCLEO_F401RE supports both examples, so we limit the compilation
test to this target only.
Compilation with an unsupported target fails (as expected) with Mbed
CLI 2 which enforces a check on a target's availability of the
required NFC controller. Mbed CLI 1 lacks such check and always
compiles.

On Armv8 targets, the PSA interface on the non-secure side only
requires mutexes, thus we remove other RTOS overrides to reduce
memory usage in general use cases.
TF-M and PSA test applications require more RTOS resources, and
they have their own configurations defined in
mbed-os-tf-m-regression-tests.
This commit also adds missing configuration for ARM_MUSCA_B1.
