qcacld-3.0: Export max IPA interface numbers

As for Rome, currently it usually just only support two
IPA interfaces offload, if use the default value 3, which
will cause the IPA pipe setup failure issue. So export
the max IPA interface numbers, and it's better to set
the appropriate value from build file according to
different requirement for different chipset and platform.
Meanwhile, it support SMMU on the sa415 platform, so
enable SMMU for it.
