Call through powerpc_interrupt for all Book-E interrupts

Make int_external_input, int_decrementer, and int_performance_counter all
now use trap_common, just like on AIM.  The effects of this are:

* All traps are now properly displayed in ddb.  Previously traps from
  external input, decrementer, and performance counters, would display as
  just basic stack traces.  Now the frame is displayed.

* External interrupts are now handled with interrupts enabled, so handling
  can be preempted.  This seems to fix a hang found post-r329882.
