doc: board: renesas: Document SH/Aarch32/Aarch64 toolchain setup

Browse Source 
Add documents which briefly outline how to set up the SH4/Aarch32/Aarch64
toolchains, for future use in Renesas documentation. Reference all these
documents in the renesas list of boards "Arch" column.

Renesas 32-bit ARM SoC build environment setup
==============================================
In order to cross-compile U-Boot for the ARM 32-bit target, it is necessary
to install a suitable toolchain. The toolchain is available in various
distribution repositories as ``arm-linux-gnueabi-*`` or similar package.
Debian example:
.. code-block:: console
$ apt install binutils-arm-linux-gnueabi cpp-arm-linux-gnueabi gcc-arm-linux-gnueabi
Alternatively, it is possible to download prebuilt toolchain from
kernel.org cross-development toolchains page
https://www.kernel.org/pub/tools/crosstool/ .
Once the toolchain is installed, add toolchain into ``PATH`` variable:
.. code-block:: console
$ export PATH=$PATH:<path/to/arm32/toolchain/bin/>
$ export CROSS_COMPILE=arm-linux-gnueabi-

Renesas 32-bit SH4 SoC build environment setup
==============================================
In order to cross-compile U-Boot for the SH4 32-bit target, it is necessary
to install a suitable toolchain. The toolchain is available in various
