[PATCH v2 2/3] platform/x86: dell-uart-backlight: Bind through normal serdev matching

[ChunAn Wu <an.wu@canonical.com>]

The driver creates a serdev client without firmware metadata and
force-attaches its driver.

Set its name before adding it so the serdev core can match the driver
normally, then remove the manual attachment.
