arm64: Disable TTBR1 maps in EL1 When running in EL1, AArch64 knows two page table maps. One with addresses that start with all zeros (TTBR0) and one with addresses that start with all ones (TTBR1). In U-Boot we don't care about the high up maps, so just disable them to ensure we don't walk an invalid page table by accident.
