qcacld-3.0: Kbuild: Define CONFIG_ENABLE_SMMU_S1_TRANSLATION

Currently the switch -DENABLE_SMMU_S1_TRANSLATION is inferred by
examining two different configuration options. In order to clearly
separate setting the configuration from applying the configuration
create a new CONFIG_ENABLE_SMMU_S1_TRANSLATION configuration
parameter.
