When the bus is in D0i3, we can't send regular commands to the firmware. This means that we need to add a state to remember what is our d0i3 state and make sure that only d0i3 exit commands can be sent. Add flags to CMD_ flags and transport status for this purpose. Commands with CMD_HIGH_PRIO set are queued at the head of the command queue, behind other high priority commands. Commands with CMD_SEND_IN_IDLE set can be sent while the transport is idle (without taking rpm reference). Commands with CMD_MAKE_TRANS_IDLE set indicate that command completion should mark the transport as idle (and release the bus). Commands with CMD_WAKE_UP_TRANS set instruct the transport to exit from idle when this command is completed. The transport is marked as idle (STATUS_TRANS_IDLE) when the FW enters D0i3 state. This bit is cleared when it enters D0 state again. Process only commands with CMD_SEND_IN_IDLE flag while the transport is idle. Other enqueued commands will be processed only later, right after exiting D0i3.
