* Passthru commands
*
* Some platforms have sub-processors chained to each other. For example.
*
* AP <--> EC <--> PD MCU
*
* The top 2 bits of the command number are used to indicate which device the
* command is intended for. Device 0 is always the device receiving the
* command; other device mapping is board-specific.
*
* When a device receives a command to be passed to a sub-processor, it passes
* it on with the device number set back to 0. This allows the sub-processor
* to remain blissfully unaware of whether the command originated on the next
* device up the chain, or was passed through from the AP.
*
* In the above example, if the AP wants to send command 0x0002 to the PD MCU,
* AP sends command 0x4002 to the EC
* EC sends command 0x0002 to the PD MCU
* EC forwards PD MCU response back to the AP
