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

Browse Source 
commit ba562d5e54 upstream.

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.
