Brian Mak f367474b58 x86/kexec: carry forward the boot DTB on kexec
Currently, the kexec_file_load syscall on x86 does not support passing a
device tree blob to the new kernel.  Some embedded x86 systems use device
trees.  On these systems, failing to pass a device tree to the new kernel
causes a boot failure.

To add support for this, we copy the behavior of ARM64 and PowerPC and
copy the current boot's device tree blob for use in the new kernel.  We do
this on x86 by passing the device tree blob as a setup_data entry in
accordance with the x86 boot protocol.

This behavior is gated behind the KEXEC_FILE_FORCE_DTB flag.
