of: Increase MAX_PHANDLE_ARGS
arm-smmu driver uses of_parse_phandle_with_args when parsing DT information to determine stream IDs for a master device. Thus the number of stream IDs per master device is bound by MAX_PHANDLE_ARGS. To support Calxeda ECX-2000 hardware arm-smmu driver requires a slightly higher value for MAX_PHANDLE_ARGS as this hardware has 10 stream IDs for one master device. Increasing it to 16 seems a reasonable choice.
