There are multiple fixed regulators on the Odroid-C1 board. Add them so they can be used when we add the devices that need them (SAR ADC needs the 1.8V IOREF, RTC needs VDD_RTC). These are: - P5V0 is the main 5V power input - VCC3V3 / VDDIO_AO3V3 / VDD3V3: fixed regulator with 3.3V output which is supplied by P5V0 - IOREF_1V8 / VCC1V8 / VDD1V8: fixed regulator with 1.8V output which is supplied by P5V0 - VDD_RTC: fixed voltage regulator with 0.9V output which is supplied by VDDIO_AO3V3 - DDR_VDDC / DDR3_1V5: fixed voltage regulator with 1.5V output which is supplied by P5V0 - the existing TF_IO and RFLASH_VDD_EN regulators are supplied by VDDIO_AO3V3 - the existing VCCK regulator is supplied by P5V0 This does not add the missing VDDEE regulator (controlled by PWM_D) because it's not clear yet how to configure the voltage of that regulator.
