trace: Add trace events for IRQ activities

This expands the format to include the class of TRC_HW_IRQ.
This means that instead of:

CPU28  1753521436727 (+    3252)  unknown (0x0000000000802008)  [ 0x0000006c 0x4605709c 0x4605b682 0x00000000 0x00000000 0x00000000 0x00000000 ]

we now see:

CPU28  1753521436727 (+    3252)  do_irq [ irq = 108, began = 1174761628us, ended = 1174779522us ]
