Merge tag 'imx-soc-3.19' into imx/dt

The i.MX SoC update for 3.19:
 - Update i.MX6 suspend code to check DDR instead of CPU type, as the
   difference we need to handle is between LPDDR2 and DDR3, not SoCs.
 - Set anatop properly for LPDDR2 in DSM mode
 - Add support for new SoC LS1021A which integrates dual Cortex-A7
 - Add ENET initialization for i.MX6SX platform
 - Add cpufreq support for i.MX53 platform
 - Add a SNVS based poweroff driver for i.MX6 platforms
 - Use ARM  Global Timer as clocksource on VF610

Note: the change set is built on top of tag imx-fixes-3.18-2 to resolve
a conflict on file arch/arm/mach-imx/clk-vf610.c.
