arch/arc: fix atomics selection

Due to a kconfig limitation, we can't select a no-prompt symbol that
gets its dependencies by being conditionally re-defined in one or more
if-blocks, like we currently do for BR2_ARCH_HAS_ATOMICS.

As a workaround to this issue, we just redefine that symbol in the arc
if-block, like we do for all other architectures, except that in the arc
case, the default value is conditional.
