Convert CONFIG_SPL_SYS_MALLOC_SIMPLE to Kconfig

This converts the following to Kconfig:
   CONFIG_SPL_SYS_MALLOC_SIMPLE

The problem here is that a few platforms have been doing:
#ifdef CONFIG_SPL_BUILD
#define CONFIG_SYS_MALLOC_SIMPLE
#endif

instead of defining CONFIG_SPL_SYS_MALLOC_SIMPLE directly.  Correct this
and update the documentation in a few places to match usage.
