Subject: [PATCH v2 02/11] mfd: axp20x: add volatile and writeable reg ranges for VBUS power supply driver

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.
