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.  Visible
