tracing: convert irq trace points to new macros
Impact: enhancement
Converted the two irq trace point macros. The entry macro copies
the name of the irq handler, thus it is better to simply use the
TRACE_FORMAT macro which uses the trace_printk.
The return of the handler does not need to record the name, thus
the faster C style handler is more approriate.
