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.

Pull ARM SoC non-critical fixes from Olof Johansson:
"Here is a collection of fixes (and some intermixed cleanups) that were
considered less important and thus not included in the later parts of
the 3.9-rc cycle.
It's a bit all over the map, contents wise. A series of ux500 fixes
and cleanups, a bunch of various fixes for OMAP and tegra, and some
for Freescale i.MX and even Qualcomm MSM.
Note that there's also a patch on this branch to globally turn off
-Wmaybe-uninitialized when building with -Os. It's been posted
several times by Arnd and no dissent was raised, but nobody seemed
interested to pick it up. So here it is, as the topmost patch."

Clean out initialisation that is handled by SoC. Regulator
settings for Vpll (partly), Vsmps1, Vsmps2, Vsmps3 (partly),
Vrf1, Varm, Vape, Vbb, Vmod are cleaned out. They should not
be touched by the kernel.
We also update many of the initialisation values to be more
in-line with the current development efforts of ST-Ericsson
internal engineers.

The ab8500 MFD should not have knowledge about regulator-

regulator registers. As the regulator platform data is
about to grow with external regulators, this information
is moved to a new structure provided by the regulator

There is already before a register mask in the regulator driver
to allow some bits of a register to be initialized. The register
value is defined in the board configuration. This patch puts a
mask in the board configuration to specify which bits should
actually be altered. The purpose with this patch is to avoid
future mistakes when updating the allowed bits in the regulator
driver.

To prevent lots of unnecessary call-backs into platform code, we're
now using the GPIO regulator framework to control the 'enable' (en)
and 'voltage select' (vsel) GPIO pins which in turn control the
MMCI's secondary regulator settings. This already works with Device
Tree, but when booting with ATAGs we need to register it as a
platform device.
