Implement mandatory platform port functions. Receive boot arguments from bl2, populate bl33 and bl32 image entry structs, call each MTK initcall levels in these mandatory platform port functions. After bl31_main exit and handover to 2nd boot loader, mtk bl33 issues SMC and traps to TF-A to execute boot_to_kernel and then handover to Linux kernel.
