Previously sanitize_multiboot_info() was called after init_debug_pre() because the debug message can only print after uart is initialized. On the other hand, multiboot cmdline need to be parsed before init_debug_pre() because the cmdline could override uart settings and make sure debug message printed successfully. This cause multiboot info was parsed in two stages. The patch revise the multiboot parse logic that split sanitize_multiboot_info() api and use init_acrn_multiboot_info() api for the early stage. The most of multiboot info will be initialized during this stage and no debug message need to be printed. After uart is initialized, the sanitize_multiboot_info() would do sanitize multiboot info and print needed debug messages.
