*** 2.1.3 ***
- FIX: DMA not initialized under some conditions (bug 3099701).
- NEW: Added an SPI driver to the STM8 platform support.
- NEW: Added a simple STM8 SPI demo under ./testhal/STM8/SPI.
- CHANGE: Renamed most of the STM8 HAL settings macro names in order to
make names more consistent.
NOTE: ****** Make sure to use a mcuconf.h file taken from ******
