This C function should be used to do the early memory layout and init. This
is beyond my powers, so just add a TODO for the maintainer.

Various files are needlessly rebuilt every time due to the version and
build time changing. As version.h is not actually needed, remove the
include.

This patch has some parts connected together:
- Use _gd in bss section which is automatically cleared
  Location at SPL_MALLOC_END wasn't cleared at all
- Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC
  (mem_malloc_init is not called at all)
- Simplify malloc and stack init.
  At the end of SPL addr is malloc area and below is stack

Create space for dm_init where calloc is called
and malloc_base has to be initialized.

Signed-off-by: Michal Simek <michal.simek@xilinx.com>

Because it is not compatible with DM where
malloc_base has to be available early and init
has to be done in ASM.

Remove one instruction in the loop which speedup
code copying.

Compile code with -fPIC to get GOT. Do not build SPL
with fPIC because it increasing SPL size for nothing.

Setup gd from ASM to be availalbe for board_init_r.
Setting it up in spl_board_init is too late when
MALLOC is used.
Space for gd is located behind MALLOC area at the end of BRAM.

It is not used at all that's why remove it.
