When the pinmux mechanism was added in Kirkwood, the device driver
core was not yet providing the possibility of attaching pinmux
configurations to all devices, drivers had to do it explicitly, and
not all drivers were doing this.
Now that the driver core does that in a generic way, it makes sense to
attach the pinmux configuration to their corresponding devices.
This allows the pinctrl subsystem to show in debugfs to which device
is related which pins, for example:
pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41
pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42

This patch fixes a bug introduced in the v3.10 merge window.
The AB8500 External Regulator driver has recently landed upstream,
which registers each of the 3 external regulators located on the
AB8500. If these regulators are marked as 'always on', there is a
potential for power-loss. If they're not and are seemingly unused
the Regulator subsystem will attempt to disable them to save power.
This causes an issue for AUX1, AUX2 and AUX3 as they obtain their
power from EXT3. So we're specifying that here to prevent EXT3 from
being powered down.
