[PATCH 1/2] dt-bindings: connector: add pd-disable dependency

[PATCH 1/2] dt-bindings: connector: add pd-disable dependency

[Xu Yang]

When Power Delivery is not supported, the source is unable to obtain the
current capability from the Source PDO. As a result, typec-power-opmode
needs to be added to advertise such capability.

What's the impact on any users of making this a dependency?
I assume nothing negative, since this will only impact systems that
don't work properly at present?

Yes, right. Most of the user satisfy this requirement,
expect imx8mp-tx8p-ml81-moduline-display-106-av101hdt-a10.dtso.
I suppose this user can't work well, so patch#2 is added.

Thanks,
