The X-Powers AXP20X and AXP22X PMICs allow to choose the maximum voltage
and minimum current delivered by the VBUS power supply.

This adds the register used by the VBUS power supply driver to the range
of volatile and writeable regs ranges.

And I'm not sure why you specify it as volatile? The PMIC doesn't change any
of the bits in this register on its own.

Same for the AXP22x bits. So basically I think you don't need this patch.
