This patchset is to resolve an issue found with Nuvoton pinctrl driver
when it uses a generic GPIO interface. Since the generic GPIO driver
stores the bgpio_data and bgpio_dir shadow register values and later on
modify based on the stored values, any change to the pin states in
between by the pinctrl driver is lost.

gpio: gpio-mmio: Allow volatile shadow regs
pinctrl: pinctrl-npcm7xx: Set BGPIOF_VOLATILE_REG
