i3c: dw: Add support for in-band interrupts

Browse source

This change adds support for receiving and dequeueing i3c IBIs.

By setting struct dw_i3c_master->ibi_capable before probe, a platform
implementation can select the IBI-enabled version of the i3c_master_ops,
enabling the global IBI infrastrcture for that controller.
