The devices that the vchiq interface registers (bcm2835-audio, bcm2835-camera) are implemented and exposed by the VC04 firmware. The device tree describes the VC04 itself with the resources required to communicate with it through a mailbox interface. However, the vchiq interface registers these devices as platform devices. This also means the specific drivers for these devices are getting registered as platform drivers. This is not correct and a blatant abuse of platform device/driver. Add a new bus type, vchiq_bus_type and device type (struct vchiq_device) which will be used to migrate child devices that the vchiq interfaces creates/registers from the platform device/driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
