Message

This serie adds the support of the hardware semaphore block for stm32mp1 SoC.

version 2:
- fix comments done by Bjorn about clock naming, license terms in header,
  alphabetic ordering in Makefile and Kconfig and remove function
- Do not push test module in this version while waiting for feedbacks about it
