malloc_simple: Add Kconfig option for using only malloc_simple in the SPL
common/dlmalloc.c is quite big, both in .text and .data usage, therefor on some boards the SPL is build to use only malloc_simple.c and not the dlmalloc.c code. This is done in various include/configs/foo.h with the following construct: #ifdef CONFIG_SPL_BUILD #define CONFIG_SYS_MALLOC_SIMPLE #endif This commit introduces a SPL_MALLOC_SIMPLE Kconfig bool which allows selecting this functionality through Kconfig instead.
