In addition to Alternative Modes (see [1]), some of the TCPM-backed
boards (e.g. Qualcomm SM8150-HDK) can support USB-C Accessory Modes
(e.g. the Analog Audio). Add bindings and driver support for parsing
this kind of information.

Note, while it might make sense to put accessory-mode-audio and -debug
handling to typec_get_fw_cap(), I decided against it. Several existing
drivers use this function, while providing AccMode caps based on some
internal logic.

Changes since v1:

- Initialised the `mode' variable to 0 (Sergei Shtylyov)
