-Properties:
-   - compatible : should contain two values. First value must be :
-                 - " st,stm32mp157-syscfg " - for stm32mp157 based SoCs,
-                 second value must be always "syscon".
-   - reg : offset and length of the register set.
-   - clocks: phandle to the syscfg clock
-
- Example:
-         syscfg: syscon@...20000 {
-                 compatible = "st,stm32mp157-syscfg", "syscon";
-                 reg = <0x50020000 0x400>;
-                 clocks = <&rcc SYSCFG>;
-         };
