Fix fdt_platform_fixups() mem region handling. It turns out u-boot puts
several types of data into the mem-info array (DRAM, SRAM, flash). We need to extract just the DRAM entries for translation into fdt memory properties. Also, increase the number of regions we can handle from 5 to 16. Submitted by: Michal Meloun
