Drop unused macro. This was copied straight from the AM62x EVM but while meant for a second region of DDR this is not even needed for the AM62x EVM configurations and has meanwhile also been dropped there. Note that on the Verdin AM62, we do auto-detect the amount of SDRAM. While at it also update the comment noting that CFG_SYS_SDRAM_SIZE is the maximum which is only used for such auto-detection.
