efi_capsule: Move signature from DTB to .rodata
The capsule signature is now part of our DTB. This is problematic when a
user is allowed to change/fixup that DTB from U-Boots command line since he
can overwrite the signature as well.
So Instead of adding the key on the DTB, embed it in the u-boot binary it
self as part of it's .rodata. This assumes that the U-Boot binary we load
is authenticated by a previous boot stage loader.
