Subject: [PATCH] Add support for (Horaco) ZX310S-4T2XH

Add support for the ZX310S-4T2XH switch, which is a 4x2.5GBit + 1x10GBit + SFP
device. The device does not have any branding and is sold under different
brand names, in particular by Horaco. There is no branding on either label
nor PCB.

CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV
10GBit PHY: RTL8261BE

UART header present, but solder holes are filled with solder that needs
removal, first, e.g with a 1.2mm drill.

The original firmware uses 57600baud 8N1
