Enables support for the in-kernel MPIC that thas been merged into the
KVM next branch.  This includes irqfd/KVM_IRQ_LINE support from Alex
Graf (along with some other improvements).

Note from Alex regarding kvm_irqchip_create():

  On x86, one would call kvm_irqchip_create() to initialize an
  in-kernel interrupt controller.  That function then goes ahead and
  initializes global capability variables as well as the default irq
  routing table.

  On ppc, we can't call kvm_irqchip_create() because we can have
  different types of interrupt controllers.  So we want to do all the
  things that function would do for us in the in-kernel device init
  handler.

This is a little strange. It is lowering the parent IRQ pin on input
when HIE is cleared. There is no such behaviour in the real hardware.

ISR changes based on interrupt pin state are already guarded on HIE
being set. So we can just delete this if in its entirety.

When the Hardware Interrupt Enable (HIE) bit is set, software cannot

Acking a level sensitive interrupt should have no effect if the
interrupt pin is still asserted. The current implementation requires
and edge condition to occur for setting a level sensitive IRQ, which
means an ACK can clear a level sensitive interrupt, until the original
source strobes the interrupt again.

Fix by keeping track of the interrupt pin state and setting ISR based
on this every time update_irq() is called.

For level sensitive interrupts, ISR bits are cleared when the input pin
is lowered. This is incorrect. Only software can clear ISR bits (via
IAR or direct write to ISR with !MER(2)).
