PrePeiUniCore was already named rather awkwardly, but now that the UniCore bit has become redundant too, let's rename it in a way that conveys its purpose a bit better: Sec. This also matches what other architectures and platforms tend to provide. A straight rename would break all out-of-tree users, so clone it into a new module with a fresh GUID, giving users some time to update. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
