In order to allow drivers/irqchip/irq-bcm7038-l1.c to be built as a
module and usable in GKI, export cpu_logical_map or __cpu_logical_map
towards the modules.

This is the usage:

#ifdef CONFIG_SMP
        cpu = intc->cpus[cpu_logical_map(smp_processor_id())];
#else
        cpu = intc->cpus[0];
#endif

This is totally broken! cpu_logical_map() takes the logical cpu
number, 0-N, and returns the MPIDR which you then use as an array
index.
