powerpc/powernv: Machine check and other system interrupts
OPAL can handle various interrupt for us such as Machine Checks (it
performs all sorts of recovery tasks and passes back control to us with
informations about the error), Hardware Management Interrupts and Softpatch
interrupts.
This wires up the mechanisms and prints out specific informations returned
by HAL when a machine check occurs.
