From: Alan Tull <atull@opensource.altera.com>
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
