PPC: Bring EPR support closer to reality

We already used to support the external proxy facility of FSL MPICs,
but only implemented it halfway correctly.

This patch adds support for

  * dynamic enablement of the EPR facility
  * interrupt acknowledgement only when the interrupt is delivered

This way the implementation now is closer to real hardware.
