[U-Boot] [PATCH 06/12] arc: add selection of endianess in Kconfig

[Alexey Brodkin]

This change allows to keep board description clean and minimalistic.
This is especially helpful if one board may house different CPUs with
different features.

It is applicable to both FPGA-based boards or those that have CPUs
mounted on interchnagable daughter-boards.
