arm/stm32f405: Fix realization of "stm32f2xx-adc" devices
stm32f405_soc_initfn() creates six such devices, but stm32f405_soc_realize() realizes only one. Affects machine netduinoplus2. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. The five unrealized devices appear to stay unreal: neither MMIO nor IRQ get wired up. Fix stm32f405_soc_realize() to realize and wire up all six.
