[ARC] Fix logic set UNALIGNED_ACCESS

gcc/
xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

	* config/arc/arc-c.def (__ARC_UNALIGNED__): Set it on
	unaligned_access variable.
	* config/arc/arc.c (arc_override_options): Set unaligned access
	default on for HS CPUs.
	* config/arc/arc.h (STRICT_ALIGNMENT): Fix logic.
