While building for NOMMU link time error shows up:

arch/arm/kernel/built-in.o: In function `setup_arch':
arch/arm/kernel/smccc-call.o:(.init.text+0xa50): undefined reference to `erratum_a15_798181_init'

It happens because erratum_a15_798181_init() lives under smp_tlb.c
which is build only for MMU configurations. So do call this function
only if build with CONFIG_MMU.
