If this driver being loaded from devicetree, the pdata is NULL. This
cause kernel Oops when "fsl,mc13xxx-uses-codec" and/or
"fsl,mc13xxx-uses-touch" properties is specified.
Well, the codec and touch are not supported if DT is used, thus why
bothering ? Just don't specify thoses properties.
IMHO it would be better to either implement full DT support in the
subdevices or removing the check for the fsl,mc13xxx-uses-codec and
fsl,mc13xxx-uses-touch in mc13xxx_probe_flags_dt().
If it's not supported let's not lie about it.
