This patch is used for IOC mediator debugging. Due to IOC message logs are
too much, need to save into one file instead of output stdout directly.
By default, the debug log is disabled.

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.
