i3c: master: Add helper to query bus wakeup requirements
Add i3c_master_has_wakeup_enabled_devs(), which iterates over the devices
on an I3C bus and reports whether any of them are enabled for system
wakeup and have IBI enabled.
Controller drivers can use this helper to determine whether wakeup
support must remain available while the system is suspended.
