Adding a new target of HW development kit using [Samsung Exynos i S111](https://www.samsung.com/semiconductor/minisite/exynos/products/iot/exynos-i-s111/) module to Mbed-OS.
This will widen the HW choices of Mbed-OS enabled NB-IoT, GNSS and Security (eFuse, AES, SHA-2, PKA, Secure Storage, Security Sub-System, [PUF](https://en.wikipedia.org/wiki/Physical_unclonable_function)) modules.

Enabled heap_and_stack test for baremetal.
Added a test to check that global variables are initialised.
In mbed_sdk_boot:
- Added initialisation for mbed_stack_isr_start/size and mbed_heap_start/size for all toolchains.
- ARM toolchain:
- Added call to mbed_toolchain_init() to initialise global variables.
- Moved microlib initialisation code from mbed_retarget.cpp to mbed_sdk_boot.c.
- IAR toolchain: there is no equivalent to a software init hook that can be called. __low_level_init() was used but since this function is called before RAM initialisation, it cannot be used to initialize global variables. Defined a new __mbed_init() function called from IAR startup file instead.
Separates SFDP header retrieval and moves it as a part of the earlier
introduced SFDP file.
Purpose is to abstract away differences between SPIF and QSPIF devices
when it comes to fetching the SFDP headers from a device.
Make an exception for this target and enable lp-ticker when LSE is not available.
This exception is added because of with disabled lp-ticker (and BLE feature) we have the following linker error with ARM compiler:

It looks like the folloiwng library must be updated:
