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.
