David Gibson ff9d2afa61 pseries: Remove XICS irq type enum type
Currently the XICS interrupt controller emulation uses a custom enum to
specify whether a given interrupt is level-sensitive or message-triggered.
This enum makes life awkward for saving the state, and isn't particularly
useful since there are only two possibilities.  This patch replaces the
enum with a simple bool.
