At present if CONFIG_ARMV7_LPAE is defined then mmu_setup() will use instructions which are invalid on ARMv4T. This happens on Tegra since it has an ARMv4T boot CPU. Add a check for the architecture version to allow the code to be built. It will not actually be executed by the boot CPU, but needs to compile.
