To support i.MX7D Low Power State Retention IOMUXC, commit e7b37a522a
("pinctrl: freescale: imx: allow mux_reg offset zero") changes the way
of zero mux_reg offset support with a new flag ZERO_OFFSET_VALID. But,
unfortunately, it forgot to add this flag for vf610 pinctrl which has
zero mux_reg offset be valid as well, and hence breaks the vf610
support.
Fix the regression by adding flag ZERO_OFFSET_VALID for vf610 pinctrl
driver.
