If CONFIG_SYS_ICACHE_OFF and CONFIG_SYS_DCACHE_OFF are set, we see the
following errors while compiling u-boot:
arch/arm/cpu/armv8/cpu.c:60: undefined reference to `icache_disable'
aarch64-linux-gnu-ld.bfd: arch/arm/cpu/armv8/cpu.c:68: undefined reference to

While the following error message is expected when SYS_DCACHE_OFF is
set:
arch/arm/cpu/armv8/cache_v8.c:697:2: error:
#error Please describe your MMU layout in CONFIG_SYS_MEM_MAP and enable
dcache.
the rest of the compilation errors should be fixed.
