Ard Biesheuvel 93be2859e2 efi: x86: Wire up IBT annotation in memory attributes table
UEFI v2.10 extends the EFI memory attributes table with a flag that
indicates whether or not all RuntimeServicesCode regions were
constructed with ENDBR landing pads, permitting the OS to map these
regions with IBT restrictions enabled.

So let's take this into account on x86 as well.
