Subject: [PATCH 19/20] ARC: Fix malformed ARC_EMUL_UNALIGNED default

'default N' should be 'default n', though they happen to have the same
effect here, due to undefined symbols (N in this case) evaluating to n
in a tristate sense.

Remove the default from ARC_EMUL_UNALIGNED instead of changing it. bool
and tristate symbols implicitly default to n.

Discovered with the
https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py
script.
