armv8: ls2080a: Drop early MMU for SPL build
Early MMU improves performance especially on emulators. However, the early MMU is left enabled after the first stage of SPL boot. Instead of flushing D-cache and dealing with re-enabling MMU for the second stage U-Boot, disabling it for SPL build simplifies the process. The performance penalty is unnoticeable on the real hardware. As of now, SPL boot is not supported by existing emulators. So this should have no impact on emulators.
