realtek: add generic support for Zyxel XS1930 lineup

Add generic support for Zyxel's XS1930 10G switch lineup. This will be
used by subsequent patches to share common behavior/settings.

Common specs:

- Realtek RTL9313 switch SoC
- 256MB RAM
- 32MB Flash with shared layout
- different 10G copper/SFP port configurations

The devices use a proprietary software chain from Zyxel, consisting of:
- stripped-down, heavily modified U-boot masked as "Bootbase"
- BootExtension stage2 loader
- Thread-X based ZyNOS

Those devices require to add some symbols to the kernel config, i.e.
CONFIG_AQUANTIA_PHY for the used PHYs and symbols for GPIO peripherals
and muxes due to the hardware design.
