Move boards to boards folder

* boards: rename configs folder to boards

    This is the proposed layout after the change:

    boards: - folder containing board folders
            <board>: - name of each board
                    drivers: - extra drivers specific for platform
                    include: - header files for the boars
                    scripts: - extra scripts specific for platform
                        src: - board specific code
                      tools: - extra tools specific for platform
                    <config>: - board specific configuration(s)

    Note:
    <xxx> names are dependent on platform

    This is a logical change to aim to the arch layout but this is a
    huge change it should be done in several steps to lower the risk.

STATUS
======
05/17: The basic NSH configuration is functional and shows that there is
3-4KB of free heap space. However, attempts to extend this have
failed. I suspect that 8KB of SRAM is insufficient to do much
with the existing NSH configuration. Perhaps some fine tuning
can improve this situation but at this point, I think this board
is only useful for the initial STM32 F0 bring-up, perhaps for
embedded solutions that do not use NSH and for general
experimentation.
There is also support for the Nucleo boards with the STM32 F072
and F092 MCUs. Those ports do not suffer from these problems and
seem to work well in fairly complex configurations. Apparently 8KB
is SRAM is not usable but the parts with larger 16KB and 32KB SRAMs
are better matches.
