Peng Fan 7a7bfec39e pinctrl: imx7ulp: Add new info instance for iomuxc1
To i.MX7ULP, we need to create two info instances for
iomux0 and iomux1 respectively, otherwise iomuxc0/1 will
share one info instance and use one base, because imx_pinctrl_probe
will use info to store base address and etc. But iomuxc0/1
actually have different base address.
