ARM: aarch64: mmu: drop ttb check when disabling the MMU
If the MMU is enabled then we should be able to disable it, no
matter if we initialized it in barebox or not. This change is not
really needed but helps when we are starting second stage from U-Boot
with the 'go' command which leaves the MMU enabled.
