Patch 1: socfpga: hotplug: put cpu1 in wfi
  Use WFI when putting CPU1 to sleep.  Don't hold CPU1 in reset
  since that results in increased power consumption.  Only
  briefly reset CPU1.

Patch 2: socfpga: support suspend to ram
  * allocate space in ocram using sram driver
  * Add a function in ocram to do suspend to ram and
    place DDR in self-refresh
