greybus: Documentation/sysfs: add example control devices
Add control devices to the example sysfs tree.
Control devices are named
<bus_id>-<module_id>.<intf_id>.ctrl
and expose attributes that are specific to the greybus interface type.
Specifically, dummy interfaces do not have a control device.
Currently, only the vendor and product strings extracted from the
manifest are exported.
A subtree of the example tree now looks as follows:
greybus1/
├── 1-5
│ ├── 1-5.5
│ │ ├── 1-5.5.2
│ │ │ ├── bundle_class
│ │ │ ├── bundle_id
│ │ │ └── state
│ │ ├── 1-5.5.ctrl
│ │ │ ├── product_string
│ │ │ └── vendor_string
│ │ ├── ddbl1_manufacturer_id
│ │ ├── ddbl1_product_id
│ │ ├── interface_id
│ │ ├── product_id
│ │ ├── serial_number
│ │ └── vendor_id
│ ├── 1-5.6
│ │ └── interface_id
│ ├── eject
│ ├── module_id
│ └── num_interfaces
└── 1-svc
