Add DT additions required by U-Boot SPL to bring up the hardware. This includes binman node to generate STM32 Image v2.0 which can be booted by the BootROM, clock entries used by the SPL clock driver during clock tree initialization, and syscon-reboot node so U-Boot can reset the system without having to rely on PSCI call.
