Wendy Elsasser ca0fd665dc 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
