usb: typec: ucsi: Expand SOP/SOP' Discovery

Hi Heikki,

This patch series expands support for partner and cable discover in the UCSI driver. There are a few pieces here.

1. Some cleanup of the GET_CABLE_PROP definitions in ucsi.h.
2. Cable discovery and registration with the USB Type-C connector class.
3. Partner/Cable identity registration with the USB Type-C connector class.
4. SOP' alternate mode registration with the USB-C connector class using a cable plug.

These have been tested on a the usb-testing branch merged with a chromeOS 6.8-rc2 kernel. Let me know if you have any questions.

Thanks,
Jameson

Changes in v2:
- Re-ordered memset call and null assignment when unregistering partners and cables.
- Supports registering partner and cable identity with UCSI versions before v2.0.
- Shortened lines to within 80 characters with the exception of two error log lines with three indentations.
- Tested on usb-testing branch merged with chromeOS 6.8-rc2 kernel.
