Add SPL specific DT additions to DH STM32MP13xx DHCOR DHSBC . These include I2C3 configuration which is required to access the PMIC, PMIC regulator and QSPI NOR bootph-all properties to allow SPL to configure PMIC buck regulators and load from QSPI NOR respectively, etzpc bus switch to simple-bus to prevent interference from TFABOOT specific configuration, and RCC configuration to define clock tree configuration used by this platform.
