So this macro, CONFIG_SPL_MALLOC_SIZE, now contains the value which used
to be in macro CONFIG_SYS_SPL_MALLOC_SIZE before patch 15/20 . In patch
15/20 , the macro CONFIG_SYS_SPL_MALLOC_SIZE was changed to be 256 .

Things are starting to be really chaotic here and it's not really clear
why these macros are really needed. Can we please clear this situation
up ?
