CXL device events are signaled via interrupts. Each event log may have
a different interrupt message number. These message numbers are
reported in the Get Event Interrupt Policy mailbox command.
Add interrupt support for event logs. Interrupts are allocated as
shared interrupts. Therefore, all or some event logs can share the same
message number.
