The X-Powers AXP209 and AXP20X PMICs are able to set a limit for the
VBUS power supply for both max current and min voltage supplied. This
series of patch adds the possibility to set these limits from sysfs.

Also, the AXP223 PMIC shares most of its behaviour with the AXP221 but
the former can set the VBUS power supply max current to 100mA, unlike
the latter. The AXP223 VBUS power supply driver used to probe on the
AXP221 compatible. This series of patch introduces a new compatible for
the AXP223 to be able to set the current max limit to 100mA.

With that new compatible, boards having the AXP223 see their DT updated
to use the VBUS power supply driver with the correct compatible.

This series of patch also migrates from of_device_is_compatible function
to the data field of of_device_id to identify the compatible used to
probe. This improves the code readability.

Mostly cosmetic changes in v2 and adding volatile and writeable regs to
AXP20X and AXP22X MFD cells for the VBUS power supply driver.

Applied all the DT patches. I also fixed all the prefixes. Please make
sure to look at what prefixes are used by a given subsystem next time.

Thanks!
