r8152: add PID for the Lenovo OneLink+ Dock

commit 1bd3a383075c64d638e65d263c9267b08ee7733c upstream.

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as
a broken CDC device by default. Add the custom Lenovo PID to the r8152
driver to support it properly.

Also, systems compatible with this dock provide a BIOS option to enable
MAC address passthrough (as per Lenovo document "ThinkPad Docking
Solutions 2017"). Add the custom PID to the MAC passthrough list too.

Tested on a ThinkPad 13 1st gen with the expected results:

passthrough disabled: Invalid header when reading pass-thru MAC addr
passthrough enabled:  Using pass-thru MAC addr XX:XX:XX:XX:XX:XX
