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.
