Backport changes from public src release (ARMmbed#94)

* Backport changes from public src release

- Add note about Flash Layout in README
- Fix compilation by polyfilling a pal function
- update dependency to 1.3 RC13
- Expecitly set SOTP config file
- Remove size data as out of date
- Fix make_release.py script as the release single
  target feature broke normal release of all features

* Add sotp config to test config file

* Rename mbed-printf to minimal-printf

+### Notes on Flash Layout
+- Internal Flash Only layout can be enabled by compiling the bootloader with the internal_flash_sotp.json configuration file `--app-config configs/internal_flash_sotp.json`. By default the firmware storage region and filesystem is on [external sd card](#external-storage).
+- The default flash layout is tested with GCC_ARM compiler and tiny.json compiler profile only. If a different compiler is used, the bootloader binary size will be larger and the offsets needs to be adjusted.
+- The SOTP regions require 1 flash erase sector each with at least 1k of space.
+- The LittleFS requires 2 flash sectors per folder and 1 sector per file as well as 2 sectors for the filesystem itself.
+
 ### Alignment
 **Flash Erase Boundary**: Flash can usually only be erased in blocks of specific sizes, this is platform specific and hence many regions need to align to this boundary.
