GEN8+ HW has the option to route PM interrupts to either the CPU or to
GT. For GEN8 this was already set correctly to routing to CPU, but not
for GEN9, so fix this. Note that when disabling RPS interrupts this was
set already correctly, though in that case it didn't matter much except
for the possibility of spurious interrupts.
