[U-Boot] [PATCH] arc: make AXS101 default platform

[Alexey Brodkin]

This fixes building in automated flow that doesn't use defconfigs.

See discussion on that topic here:
 http://patchwork.ozlabs.org/patch/502558/

See similar patches for other architectures/platforms  here:

And while at it add missing shell prompt to axs103.
