Hans de Goede 1d624a4f08 sunxi: axp: Move axp pmic register helpers to a separate file
Move the register helpers used to access the registers via p2wi resp.
rsb bus on the otherwise identical axp221 and axp223 pmics to a separate
file, so that they can be used by the upcoming standalone axp gpio driver
too.
