[PATCH 3/9] tty_port: make tty_port_register_device wrap tty_port_register_device_attr

[Rob Herring <robh@kernel.org>]

tty_register_device is just a wrapper for tty_register_device_attr with
NULL passed for drvdata and attr_grp. So similarly make
tty_port_register_device a wrapper of tty_port_register_device_attr so that
additions don't have to be made in both functions.
