realtek: add Zyxel GS1900-48HP A1 support

Browse Source 
Add support for the Zyxel GS1900-48HP A1 managed PoE switch based on
RTL8393 SoC with 48 copper ports (6x RTL8218B), 2 SFP slots and PoE
(170W budget). Includes DTS, image definition, network config and
u-boot-env support.

The device has 48 copper ports but only ports 1-24 are powered by
the PoE PSE controller.

PoE support requires the realtek-poe package from the packages feed
with an additional configuration for PSE ID 7 to address the MCU on
this device.
