[PATCH v2 0/2] USB Type-C mode selection

[Andrei Kuchynski]

This patch series introduces priority-based alternate mode selection
support for cros_ec_typec. 
The base patch series and UCSI support was submitted here:

When AP-driven alternate mode selection is active, the driver enforces the
mode_selection bit for each registered Alternate Mode. This blocks
individual altmode drivers from self-activating. Once registration
completes, the driver evaluates USB4 capability. If USB4 is unsupported,
it falls back to priority-based negotiation via typec_mode_selection_start.

Additionally, we swap the registration sequence of the port's alternate
modes. Registering DisplayPort after Thunderbolt correctly ensures DP is
prioritized.

Changes in v2:
- Added this cover letter.
- Rebased on top of the latest platform-chrome tree.
- Tested on Redrix with Linux Fedora 7.3.0-rc5+.
