commit 9571b25df1dbf4db17191b54f59734e8b77fd591 upstream.

imx1_pinconf_set assumes that the array of pins in struct
imx1_pinctrl_soc_info can be indexed by pin id to get the
pinctrl_pin_desc for a pin. This used to be correct up to commit
607af165c047 which removed some entries from the array and so made it
wrong to access the array by pin id.

The result of this bug is a wrong pin name in the output for small pin
ids and an oops for the bigger ones.

This patch is the result of a discussion that includes patches by Markus
Pargmann and Chris Ruehl.
