ARM: Allow kernel unaligned accesses on ARMv6+ processors

Browse Source 
Recent gcc versions generate unaligned accesses by default on ARMv6 and
later processors. This patch ensures that the SCTLR.A bit is always
cleared on such processors to avoid kernel traping before
alignment_init() is called.
