Pull request overview

This PR introduces an OEM customization hook for the Type-C controller Port by adding a Customization trait and making Port generic over a customization implementation (defaulting to DefaultCustomization). The main behavioral change is that consumer power capability flags (notably unconstrained power) are now derived via the customization layer rather than directly from controller config. As part of this, the previous controller::config::Config content is removed and an explicit Port::with_customization(...) constructor is added for injecting non-default customization.

Changes:

• Add controller::customization module defining Customization, DefaultCustomization, and UnconstrainedSink.
• Make controller::Port generic over a Customization implementation (defaulted) and thread it through controller trait impls.
• Route consumer capability updates through Customization::update_consumer_capability(...) during sink contract processing.
