[ARM] 3810/1: switch atomic helpers over to raw_local_irq_{save,restore}

Now that we have raw_* variants of local_irq_$FOO(), switch the atomic
helpers over to use those raw_* variants.  This is necessary when using
lockdep on pre-ARMv6 hardware, as lockdep uses atomic_t counters in the
trace_hardirqs_off() path.
