This patch adds a has_xsm_magic helper function for detecting XSM
from the second unknown module.

If Xen can't get the kind of module from compatible, we guess the kind of
these unknowns respectively:
     (1) The first unknown must be kernel.
     (2) Detect the XSM Magic from the 2nd unknown:
         a. If it's XSM, set the kind as XSM, and that also means we
        won't load ramdisk;
        b. if it's not XSM, set the kind as ramdisk.
        So if user want to load ramdisk, it must be the 2nd unknown.

The documentation in docs/misc/arm/device-tree/booting.txt needs to be update.

Otherwise, the rest of the patch looks good to me.
