Pull "i.MX cleanup for 4.9" from Shawn Guo:

 - Drop i.MX1 board files and make i.MX1 a DT only platform.
 - Remove obsolete ENET initialization code for TX28 board, since FEC
   driver handles those setup well now.
 - A couple of cleanups on i.MX31 IOMUX headers to drop duplications
 - A few other random and trivial cleanups
