Ziyi Cui 05760b29af ANDROID: softirq: Add EXPORT_SYMBOL_GPL for softirq and tasklet ...

The purpose of these symbols is for getting irq/softirq latency. Currently we only have symbols for irq_handler_entry and irq_handler_exit. We would use these latency for further monitoring and debugging.

The related tracepoints were defined in trace/events/irq.h. We would use these tracepoints in vendor kernel module.
