Previously, the Allwinner Parrot R16 used everything declared in AXP221
DTSI while it has an AXP223 PMIC.
This corrects that so the Allwinner Parrot R16 can get some features the
AXP223 has (at the moment, ability to have 100mA as maximal current on
VBUS power supply).

I'm not really fond of using this boolean as I don't see it being
possibly reused for any other SoCs that has a GPADC or THS.
Here, you could make use of a list/array of clk which then can be reused
for other SoCs just by changing the list. Add

The OPP are declared as shared but no operating points are declared for
cpu1, 2 and 3. Thus, the following error happens during the boot:

This patch applies the operating points to each cpu of the A33.

boards defining the CPU regulator, we cannot have these
two frequencies as it would cause the CPU to try to run a higher
frequency without "overvolting" which is very likely to crash the CPU.
Therefore, these two frequencies must be enabled on a per-board basis.

that will require to create a DT binding for this IP, we can
avoid using an MFD, thus we need two separate functions: one for probing
via MFD and one for probing without MFD.
This split the code specific to MFD probing in a function separated from
the driver probe function.

The X-Powers AXP20X and AXP22X PMICs expose the status of AC power

This adds the AC power supply driver to the MFD cells of the AXP22X
