Previousely the efi_info structure in acrn_boot_info struct is defined as same as Linux kernel so that the native efi info from host could be passed to SOS zeropage with memcpy() api directly. Now replace it with abi_efi_info struct to make the content more generic; Tracked-On: #5661 Signed-off-by: Victor Sun <victor.sun@intel.com> Reviewed-by: Jason Chen CJ <jason.cj.chen@intel.com>
