I3C: Command execution may fail during slave-initiated IBI address byte reception
An SoC host command to the I3C controller may lead to improper command execution by the controller, including incorrect frame generation, if the command was written while a slave-initiated IBI address byte reception is in progress.
In such case, the command response queue is incorrectly filled with responses. Additionally, if received IBI has no payload and is ACKed by Master, then slave fetched command causes incorrect frame issued over bus.
Host needs to disable IBI by sending Broadcast DISEC CCC before sending commands to the controller.
