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

Patch 1: socfpga: hotplug: put cpu1 in wfi
Fix how cpu1 is hotplugged to prevent increased power
consumption.

v2: no need to flush the caches
clean up spacing in comments
replace a register offset with a macro

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

v2: use Generic on-chip SRAM driver to allocate ocram
rm fncpy_align since generic allocator handles alignment
check __arm_ioremap_exec return code
check for NULL pointers
add a comment regarding sdram controller configuration
