pinctrl: freescale: add ZERO_OFFSET_VALID flag for vf610 pinctrl

To support i.MX7D Low Power State Retention IOMUXC, commit e7b37a522aa9
("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.
