sysreset: socfpga: soc64: Enable L2 reset
Put all slave CPUs (CPU1-3) into WFI mode. Master CPU (CPU0) writes the magic word into system manager's scratch register to indicate the system has performed L2 reset and request reset manager to perform hardware handshake and then trigger L2 reset. CPU0 put itself into WFI mode. L2 reset will reboot all HPS CPU cores after which all HPS cores are in WFI mode. L2 reset is followed by warm reset request by SPL via RMR_EL3 system register.
