[PATCH RFC 09/14] common/board_f: init malloc earlier

Currently the early malloc initialisation is done partially in
board_init_f_init_reserve() (on arm64 at least), which configures
gd->malloc_base. But it isn't actually usable until initf_malloc() is
called which doesn't happen until after fdtdec_setup().

This causes problems in a few scenarios:

1. when using MULTI_DTB_FIT as this needs a working malloc (especially
   for compressed FIT).
2. Some platforms may need to allocate memory as part of memory map
   initialisation (e.g. Qualcomm will need this to parse the memory map
   from SMEM).

Move the initf_malloc() call earlier so that malloc is available during
fdtdec_setup().
