This patch adds a new SYSCFG peripheral used by the STM32L4x5 SoC.
The implementation is inspired from the STM32F4xx SYSCFG, the device
registers however aren't the same.

The patch is split up in 3 commits :
- implementing the SYSCFG device
- adding tests (that fail in this commit)
- connecting the SYSCFG device to the SoC (the tests pass in this
commit)
