arm64: dts: ti: verdin-am62: Set VDD CORE minimum voltage to 0.75V
Set VDD_CORE minimum voltage to 0.75V, TI AM62 can run at either 0.75V or 0.85V depending on the actual speed grade and on the maximum configured speed (1.4GHz frequency requires 0.85V). The actual value is programmed into the PMIC EEPROM during manufacturing (according to the SOC speed grade) and this ensure that both the voltage values are valid and therefore the OS will not overwrite the value programmed into the PMIC.
