greybus: define greybus interface abstraction Define new source files "interface.h" and "interface.c" to contain the definitions of the Greybus interface abstraction. A Greybus interface represents a UniPro device present in a UniPro module. For Project Ara, each interface block on a module implements a UniPro interface.

greybus: hook up greybus to the driver model This patch hooks up modules, interfaces, and connections to the driver model. Now we have a correct hierarchy, and drivers can be correctly bound to the proper portions in the future. Devices are correctly reference counted and torn down in the proper order on removal of a module. Some basic sysfs attributes have been created for interfaces and connections. Module attributes are not working properly, but that will be fixed in future changes. This has been tested on Alex's machine, with multiple hotplug and unplug operations of a module working correctly.

greybus: October 1 updates Update the definitions in "greybus_manifest.h" to reflect the changes to the Greybus specification made on October 1. They are: - renaming "device" to be "interface" - renumbering greybus descriptor type - eliminating the notion of a "function" - defining a CPort's protocol in the CPort descriptor - having a "class" take on the types previously used for "function" - renaming "serial number" to be "unique id" (for now) - relying on an interface's maximum cport id to determine how much device+cport address space the interface consumes - adding a simple class descriptor - renaming gb_interface->interface_id to be gb_interface->id This also reorders some things to match ordering in the document, and adds some commentary for the various structures. Since greybus_function_type is gone, we eliminate the "type" field from a function structure. (Functions are going away, next.)
