Markus Pargmann 16837f9588 pinctrl: fsl: imx: Check for 0 config register 
0 is used in all pinfunction definitions when a config register is not
available, for example imx25-pinfunc.h. If a configuration value is used
for such a pinfunction the driver will always write it to the
configuration register if it is not -1. For a 0 configuration register
the configuration value is written to offset 0x0. This can lead to a
crashing/hanging system without any warning message.

This patch checks for 0 config register and sets the internal value to
-1. If the configuration value is not NO_PADCTL this leads to an error
message that applying the configuration failed.
