i3c: master: svc: Modify enabled_events bit 7:0 to act as IBI enable counter
commit 25bc99be5fe53853053ceeaa328068c49dc1e799 upstream.
Fix issue where disabling IBI on one device disables the entire IBI
interrupt. Modify bit 7:0 of enabled_events to serve as an IBI enable
counter, ensuring that the system IBI interrupt is disabled only when all
I3C devices have IBI disabled.
