You are using the function qpic_pad which is not supported for some of the 
GPIOs (according to 852-ipq4019-pinctrl-Updated-various-Pin-definitions.patch [1]):

    [    1.067122] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio57" for function "qpic_pad"
    [    1.068305] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio58" for function "qpic_pad"
    [    1.076685] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio59" for function "qpic_pad"
    [    1.084991] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio60" for function "qpic_pad"
    [    1.093351] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio64" for function "qpic_pad"
    [    1.101653] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio65" for function "qpic_pad"
    [    1.109987] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio66" for function "qpic_pad"
    [    1.118319] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio67" for function "qpic_pad"
    [    1.126652] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio68" for function "qpic_pad"

* "gpio57" would be qpic_pad4
* "gpio58" would be qpic_pad5
* "gpio59" would be qpic_pad6
* ....
