35acdbe909 realtek: merge Zyxel GS1900 firmware partitions
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.

To maintain install capabilites on new devices, an image is required
that still fits inside the original partition. The initramfs is used as
factory install image, so ensure this meets the old size constraints.
The factory image can be flashed via the same procedure as vendor images
when reverting to stock, can be installed from stock, or can be launched
via tftpboot.

2ada95ccdf realtek: ZyXEL GS1900-48: drop gpio-restart
GPIO 5 on the RTL8231 is defined reset the system, but fails to actually
do so. This triggers a kernel a number of warnings and backtrace for
GPIO pins that can sleep, such as the RTL8231's. Two warnings are
emitted by libgpiod, and a third warning by gpio-restart itself after it
fails to restart the system:

By removing gpio-restart from this device, we skip the restart-by-GPIO
attempt and rely only on the watchdog for restarts, which is already the
de facto behaviour.

0b078f2ecf realtek: normalize dts directory
There is no need to keep a version specific dts directory.
Rename the folder to its standard location.
