[PATCH 1/3] sh: Set gd->malloc_base if MALLOC_F_LEN is set
The gd->malloc_base must be set before the C runtime if the MALLOC_F_LEN is non-zero, otherwise we hit assertion in dlmalloc.c initf_malloc(). So set it.

Add simple DT and clock bindings to r2dplus DT to permit U-Boot to bind the SCIF driver via DT probing instead of hard-coded config options.
