Add a wrapper API init_acrn_boot_info() so that it could be used to boot ACRN with any boot protocol; Another change is change term of multiboot1 to multiboot because there is no such term officially; Tracked-On: #5661 Signed-off-by: Victor Sun <victor.sun@intel.com> Reviewed-by: Jason Chen CJ <jason.cj.chen@intel.com>
