Merge "ARM: imx: cleanup for 3.18" from Shawn Guo:

The i.MX cleanup for 3.18:
 - Reomve a few i.MX27 and i.MX1 board files
 - Remove imx_scu_standby_enable() since core code handles scu
   standby now
 - Remove unnecessary iomux declaration
 - Remove useless sound card property from vf610-twr dts

  ARM: imx: Remove mach-mxt_td60 board file
  ARM: i.MX: Remove i.MX1 ADS board support
  ARM: dts: vf610-twr: remove useless property for sound card.
