rpi3: Concatenate BL1 and FIP automatically

Add a new default makefile target to concatenate BL1 and the FIP and
generate armstub8.bin. This way it isn't needed to do it manually.

Documentation updated to reflect the changes.

BL33=../rpi3-arm-tf-bootstrap/aarch64/el2-bootstrap.bin \
all fip
Then, join BL1 and the FIP with the following instructions (replace ``release``
by ``debug`` if you set the build option ``DEBUG=1``):
.. code:: shell
cp build/rpi3/release/bl1.bin bl1.pad.bin
truncate --size=131072 bl1.pad.bin
cat bl1.pad.bin build/rpi3/release/fip.bin > armstub8.bin
The resulting file, ``armstub8.bin``, contains BL1 and the FIP in the place they
need to be for TF-A to boot correctly. Now, follow the instructions in
`Setup SD card`_.
The build system concatenates BL1 and the FIP so that the addresses match the
ones in the memory map. The resulting file is ``armstub8.bin``, located in the
build folder (e.g. ``build/rpi3/debug/armstub8.bin``). Now, follow the
instructions in `Setup SD card`_.
