247c5eeb22 IOC mediator: Send open channel command to activate CBC signal channel by default
To send open channel command after opening CBC signal channel successfully.
For the latest IOC firmware, the IOC mediator needs to send open channel command
to activate CBC signal channel. Otherwise, there will be no any signal data will
be received.

The open channel command is forward compatible that it would not impact for
older IOC firmware.

61db2c78cc IOC mediator: support IOC lifecycle
This patch implements the IOC lifecycle virtualization.

In native environment, lifecycle is uesed for SoC system power control,
likes enter/exit S3/S5. So these related messages can not forward directly
between physical IOC and Guest OS, they need to be mapped to VM pause, exit
and launch.
