This driver is checking the access rights of the different
peripherals connected to the RIFSC bus. If access is denied,
the associated device is not binded.

Cover-letter:
Enable OF_UPSTREAM for STM32 and STi platforms
This series is enabling OF_UPSTREAM flag for STM32 MCU's, MPU's and
STi platforms.
For some boards, some defconfig and DT update are needed to keep the
same functional level.
The major impact concerns MPU's platform with introduction of STM32
System Bus.
