boot/uboot: add support for the kconfig infrastructure
With the patchset "kconfig: turnaround into single .config"
[http://lists.denx.de/pipermail/u-boot/2015-February/205490.html]
U-Boot switched to a single .config file for board configuration. This
allows us to use the kconfig-package infrastructure.
For providing backward compatibility with older U-Boot version a user
choice between the new Kconfig and the legacy build system is
introduced.
[Thomas:
- make use of the legacy build system the default, to not break
existing configurations.
- add some comments in the code checking all the configuration
options, in order to hopefully make it a bit clearer.]
