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.

If you want to build SPL as well as the normal image, say Y.

+ Say Y here to only use the *_simple malloc functions from
+ malloc_simple.c, rather then using the versions from dlmalloc.c
+ this will make the SPL binary smaller at the cost of more heap
+ usage as the *_simple malloc functions do not re-use free-ed mem.
