realtek: add support for switch Zyxel GS1900-24EP

This device is very similar to the GS1900-24E switch (added in b515ad1),
except that the first 12 of 24 ethernet ports are capable of PoE and the
physical jacks are in the right order - unlike for the GS1900-24E, where
even and uneven ports are flipped (up <-> down on panel).

Zyxel version code for this device (-24EP) is: ABTO
