Subject: pinctrl: imx1-core: Fix debug output in .pin_config_set callback
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.
