This allows the module to be autoloaded.
Together with 07949bf9c63c ("cpufreq: dt: allow driver to boot
automatically") this is sufficient to allow a modular kernel (such
as Debian's) to enable cpufreq on a Cubietruck.

Add AXP22X regulator definitions and variant id associations.
This introduces a new "switch" type output for one of the regulators.
It is a switchable secondary output of one regulator, with the same
voltage level as the primary output.

Rework the AXP20X_ macros and probe function to support the several chip
families, so that each family can define it's own set of regulators.

A common simplified DT parsing code for regulators was introduced in
commit a0c7b164ad11 ("regulator: of: Provide simplified DT parsing
method"). This is very similar to our own code, so get rid of ours
and use the common code.

This patch fills the DT related fields in the regulator descriptors,
which can then be used by the regulator core's simplified DT code.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

The current device used for the regulator configuration is the child device
created by the MFD driver. This means that it doesn't have any of_node pointing
to it, and whenever we register the regulators, it will not look into the
regulator supply in the DT, hence requiring to provide regulator aliases in the
MFD driver.
We can easily fix that by using the parent device in our configuration, which
has a DT node associated to it, and will allow a DT lookup. Eventually, we will
be able to remove the aliases in the MFD driver.

The of_find_node_by_name function will search for a DT node named
"regulators" after the provided np node, but will not ensure that this node
is a child of np.
This might result in retrieving a "regulators" node that is not related to
the axp20x PMIC.
