[PATCH] pinctrl: imx: Do not treat a PIN without MUX register as an error

[Alexander Shiyan <shc_work@xxxxxxx>]

Some PINs do not have a MUX register, it is not an error.
It is necessary to allow the continuation of the PINs configuration,
otherwise the whole PIN-group will be configured incorrectly.
