[U-Boot] [RFC PATCH] sunxi: support board-specific configuration options

[Bernhard Nortmann]

Extend sunxi-common.h to include sunxi-boards.h - which in turn
can support multiple configurations/options/includes, based on
board-specific symbols (preprocessor definitions). These might
be supplied by the respective *_defconfig files.
