Initialize and sanitize a acrn specific multiboot info struct with current supported multiboot1 in very early boot stage, which would bring below benifits: - don't need to do hpa2hva convention every time when refering boot_regs; - panic early if failed to sanitize multiboot info, so that don't need to check multiboot info pointer/flags and panic in later boot process; - keep most code unchanged when introduce multiboot2 support in future; Tracked-On: #4419 Signed-off-by: Victor Sun <victor.sun@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
