mem: Update DRAM configuration names
Names of DRAM configurations were updated to reflect both the channel and device data width. Previous naming format was: <DEVICE_TYPE>_<DATA_RATE>_<CHANNEL_WIDTH> The following nomenclature is now used: <DEVICE_TYPE>_<DATA_RATE>_<n>x<w> where n = The number of devices per rank on the channel x = Device width Total channel width can be calculated by n*w Example: A 64-bit DDR4, 2400 channel consisting of 4-bit devices: n = 16 w = 4 The resulting configuration name is: DDR4_2400_16x4 Updated scripts to match new naming convention. Added unique configurations for DDR4 for: 1) 16x4 2) 8x8 3) 4x16 Change-Id: Ibd7f763b7248835c624309143cb9fc29d56a69d1 Reviewed-by: Radhika Jagtap <radhika.jagtap@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>
