realtek: Add support for Zyxel XGS1210-12 Switch

The Zyxel XGS1210-12 Switch is a 10 + 2 port multi-GBit switch with
8 x 1000BaseT, 2 x 10/100/1000/2500BaseT Ethernet ports and
2 SFP+ module slot.

Hardware:
- RTL9302B SoC
- Macronix MX25L12833F (16MB flash)
- Nanja NT5CC64M16GP-1 (128MB DDR3 SDRAM)
- RTL8231 GPIO extender to control the port LEDs
- RTL8218D 8x Gigabit PHY
- RTL8226 2x 10m/100m/1/2.5 Gigabit PHY
- SFP+ 2x 10GBit slot

Power is supplied via a 12V 1.5A standard barrel connector. At the
right side behind the grid is UART serial connector. A Serial
header can be connected to from the outside of the switch trough
the airvents with a standard 2.54mm header.
Pins are from top to bottom Vcc(3.3V), TX, RX and GND. Serial
connection is via 115200 baud, 8N1.

A reset button is accessble through a hole in the front panel

At the time of this commit, all ethernet ports work under OpenWrt,
including the various NBaseT modes, SFP+ slots are supported with i2c bus.

Installation
--------------
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* Navigate to 'Management' in the OEM web interface and click on 'Firmware upgrade'
  to the left.
* Upload the OpenWrt initramfs image, and wait till the switch reboots.
* Connect to the device through serial and change the U-boot boot command.
  > fw_setenv bootcmd 'rtk network on; boota'
* Reboot, scp the sysupgrade image to /tmp, verify the checksum and flash it:
  > sysupgrade openwrt-realtek-rtl930x-Zyxel_xgs1210-12-squashfs-sysupgrade.bin
* Upon reboot, you have a functional OpenWrt installation. Leave the bootcmd
  value as is - without 'rtk network on' the switch will fail to initialise
  the network.

Debug
------------
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* A tftp server is requiered, tftpd-hpa works well.
* Power the device, at U-Boot start rapidly hit Esc key to stop autoboot
* Enable network:
  > rtk network on
* Change ip address (default is 192.168.1.1):
  > setenv ipaddr 192.168.1.6
* Download initramfs:
  > tftpboot 0x84f00000 192.168.1.111:openwrt-realtek-rtl930x-Zyxel_xgs1210-12-initramfs-kernel.bin
* Boot loaded file:
  > bootm 0x84f00000

This prodecudre also apply to the sock firmware with the file XGS1210-12_V2.00(ABTY.1)C0.bix.

More information can be found on the page of XGS1250-12 as they share the same base.
