Todd Broch 44e4f7cfe7 usb: Groundwork for USB BOS & Billboard class descriptors. ...

The BOS (Binary Device Object Store) descriptor was added to the USB
specification (3.0) to allow a richer set of device capability
specific descriptors.

The Billboard class is meant to expose (read-only) the status of USB
devices capable of alternate mode functions.  It's required to use the
BOS descriptor type and at a high level looks like:

  - BOS Device Descriptor (5bytes)
    - Container ID Device Capability Descriptor (20bytes)
    - Billboard Device Capability Descriptor (44byte + 4 * numSVIDs)

This CL adds:
1. Ability for Get Descriptor on BOS descriptors.  Note hidden behind
CONFIG_USB_BOS as these descriptors change USB device requirements
to:
   - bcdUSB >= 0201
   - no interface descriptors

2. structures for all BOS, Container & Billboard descriptor elements
complete w/ CamelCase.

BRANCH=none
BUG=chrome-os-partner:32652
TEST=compiles with CONFIG_USB & CONFIG_USB_BOS enabled.
