arc: add selection of endianess in Kconfig
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. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
