mfd: Add ROHM BD9571MWV-M MFD PMIC driver
Add the MFD part of the ROHM BD9571MWV-M PMIC driver and MAINTAINERS entry. The MFD part only specifies the regmap bits for the PMIC and binds the subdevs together. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
