Log: Enable parsing simple-bus 'ranges' with multiple entries This patch makes possible to boot with up to 8 ranges in soc. Dynamic allocation cannot be used, because ftd_get_ranges function is called early, when malloc is not available. Change is required for the alignment of Marvell Armada 38x device trees present in sys/gnu/dts/arm - originally the platform has 6 entries in simple-bus 'ranges'.
