Support suspend to ram on socfpga. * allocate space in ocram using sram driver. * Add a function in ocram to place DDR in self-refresh and suspend. * SDRAM ECC is mutually exclusive with using ocram for suspend, so disable SDRAM ECC if socfpga suspend is enabled. * Add a device tree binding document for the Altera SOCFPGA SDRAM controller that is used to put DDR in self-refresh mode.
