Instead of loading u-boot proper image (u-boot.img), SPL now loads FIT image (u-boot.itb) which includes u-boot proper, ATF and u-boot proper's DTB.

Override 'lowlevel_init' to make sure secondary CPUs trapped in ATF instead of SPL. After ATF is initialized, it will signal the secondary CPUs to jump from SPL to ATF waiting to be 'activated' by Linux OS via PSCI call.

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).

Booting Agilex and Stratix 10 with ATF support.

SPL now loads ATF (BL31), U-Boot proper and DTB from FIT image. The new boot flow with ATF support is as follow:

SPL -> ATF (BL31) -> U-Boot proper -> OS (Linux)

U-Boot proper now starts at 0x200000 (CONFIG_SYS_TEXT_BASE). ATF will occupy the address range starting from 0x1000.
