Subject: [PATCH 1/3] usb: typec: ucsi: Stop abuse of bit definitions from ucsi.h
Date: Wed, 27 Mar 2024 23:45:52 +0100

In ucsi.h there are flag definitions for the ->flags field
in struct ucsi. Some implementations abuse these bits for
their private ->flags fields e.g. in struct ucsi_acpi.

Move the definitions into the backend implementations that
still need them. While there fix one instance where the flag
name was not converted in a previous change.

No semantic change intended.
