Working on Gigabit/PCIe support in U-Boot for Apalis T30 I realised that the current device tree source includes for our modules only happen to work due to referencing the on-carrier 5v0 supply from USB which is not at all available on-module. The modules actually contain TPS60150 charge pumps to generate the PMIC required 5 volts from the one and only 3.3 volt module supply. This patch fixes this.
