Some platforms (like socfpga A10) need a big hep before SDRAM is available
(e.g. because FAT is used). For such platforms, simple_malloc is often not
a good option as it does not support freeing memory. These platforms often
use the non-Kconfig defines CONFIG_SYS_SPL_MALLOC_START (and its SIZE).
This patch allows enabling CONFIG_SPL_SYS_MALLOC_F_LEN while leaving
CONFIG_SPL_SYS_MALLOC_SIMPLE disabled. In this case, the full malloc heap
is made available as early as the simple_malloc heap would be normally.
This way, platforms can drop the non-Kconfig options to set up the full
heap and rely on the same automatically calculated heap allocation used
for simple heap.
