arm64: Only allow dcache disabled in SPL builds
Now that we have an easy way to describe memory regions and enable the MMU, there really shouldn't be anything holding people back from running with caches enabled on AArch64. To make sure people catch early if they're missing on the caching fun, give them a compile error. Signed-off-by: Alexander Graf <agraf@suse.de>
