Some low power tickers take multiple cycles of the low power clock
to set a compare value. Because of this if the compare value is set
twice back-to-back these implementations will block until that time
has passed. This can cause system stability issues since interrupts
are disabling for this time.
To gracefully support this kind of hardware this patch adds code
to prevent back-to-back writes to the hardware. It does this by
recording the low power clock cycle of the initial write. If any
writes come in too soon after this initial write the microsecond
ticker is used to schedule the new write in the future when the
hardware is ready to accept a new value.
To enable this feature on a target the macro LOWPOWERTIMER_DELAY_TICKS
must be set to the number of low power clock cycles that must elapse
between writes to the low power timer.
The ci-shield tests that manually generate the START, STOP
by calling the HAL functions were failing. The byte operation
HAL functions cannot use the MCUXpresso SDK driver API's.

1. Add linking time preprocessor macro __DOMAIN_NS for non-secure build
2. For output .hex format, combine multiple .hex files (for multiple load regions) into one
This can help for Greentea test.
3. Fix 'None' build_dir with cmse_lib.o on Greentea test
Some platforms have interface chips with hardware flow control
enabled by default. This commit adds configurable flow control to
STDOUT.
Usage:
* Define pin names STDIO_UART_RTS for Rx-flow-control and
STDIO_UART_CTS for Tx-flow-control.
* Set target.console-uart-flow-control. Valid options are:
null, RTS, CTS, and RTSCTS.
Replace looping construct with actual block writes.
Transaction in spi_master_block_write funtion is protected by critical
section to ensure it is completed without interruption. A hardware
limitation may cause data corruption if the TX fifo is allowed to run
empty.
Compiler reminded that a variable declaration was left behind when
the code using it was put behind #ifdef. Add the missing #ifdef.
Warning being fixed:

nanostack-hal.critical-section-usable-from-interrupt -tunable was
previously added to optionally make critical section code interrupt safe.
The IRQ safe critical section is a prequisite for interrupt safe timer
callbacks.
The same flag can be used to enable calling of the timer callbacks
directly from the timer interrupt context, without bouncing them via
event thread. This removes the code and RAM consumed by EventQueue
and the thread serving the high priority events.
If the system does not have any dependencies on mbed_shared_queues,
by setting this flag the static RAM usage is now further reduced
by ~1600 bytes and code size by 4KB.
Note: the default behavior is not changed, one needs to override the
"nanostack-hal.critical-section-usable-from-interrupt" to have "true".
Any data structure used in LoRaWANBase class should be available
in a separate header in order to make the code easy to port and
easy to read as the developer doesn't need to know about all the
internal data structures being used in Mbed LoRaWAN stack.
