greybus: Documentation/sysfs: update the example sysfs tree
Update the example sysfs-tree layout under Documentation.
The new layout reflects changes to the kernel device-model that are
needed to eventually be able to handle multiple AP-bridges.
The example tree has two AP-bridges, each with its own view of the
UniPro network, the bus.

Every bus has exactly one svc device (1-svc and 2-svc). For our system,
the svc device of each bus will be a representation of the same
network-unique SVC device (e.g. endo_id and unique_id will be
identical).
The first bus has two registered interfaces (1-2 and 1-4), while the
second bus has a single interface (2-3). Note that the interface ids (2,
4, and 3) are necessarily unique as these are interfaces on the same
network.
Interface 1-2 has two bundles (1-2.1 and 1-2.2) and interface 1-4 has
a single bundle (1-4.2). The bundle ids are interface-unique and reflect
the ids found in each manifest.
In the example, bundle 1-4.2 has a gbbridge-device, which is the parent
device for a gpiochip device and an i2c bus.
