arm: socfpga: soc64: Add SMC helper function for Intel SOCFPGA (64bits) invoke_smc() allow U-Boot proper running in non-secure mode (EL2) to invoke SMC call to ATF's PSCI runtime services such as System Manager's registers access, 2nd phase bitstream FPGA reconfiguration, Remote System Update (RSU) and etc. smc_send_mailbox() is a send mailbox command helper function which invokes the ATF's PSCI runtime service (function ID: INTEL_SIP_SMC_MBOX_SEND_CMD) to send mailbox messages to Secure Device Manager (SDM).
