i3c: master: Support IBI-based wakeup capability
An I3C controller acts as a bus controller for one or more I3C devices.
If the controller can wake the system in response to an In-Band
Interrupt (IBI), then any device on that bus that is capable of
generating IBIs can potentially be used as a wakeup source.
Add an ibi_wakeup flag to struct i3c_master_controller so controller
drivers can advertise support for IBI-based wakeup.
If set, mark IBI-capable I3C devices as wakeup capable when they are
registered, allowing wakeup management through the standard device
wakeup framework.
