realtek: merge Zyxel GS1900 firmware partitions

Browse Source 
The dual-boot partition layout for the Zyxel GS1900 switches results in
6.9MB for both kernel and rootfs. Depending on the package selection,
this may already leave no space for the user overlay.

Merge the two firmware partitions, effectively dropping dual boot
support with OpenWrt. This results in a firmware partition of 13.9MB,
which should leave some room for the future.
