I suspect the hog groups are not getting initialized.

Please try:

&iomuxc {
     pinctrl-names = "default";
     pinctrl-0 = <&pinctrl_hog>;

     pinctrl_hog: hoggrp {
     fsl,pins = <
     ......
    >;
};

and then group all the hog pins under the same group.

Then check IOMUXC_SW_MUX_CTL_PAD to make sure the SION bit is set.
