Update the devicetree files to switch the GS1900 devices over to the new
pinctrl and GPIO driver. Enable the drivers to ensure the nodes can be
used.
This may fix issues caused by bad RMW behaviour on the GPIO data lines,
or glitches due to setting the pin direction before the pin level.
Although the driver supports retaining GPIO state after a warm boot,
some bootloaders appear to apply a default configuration on boot, which
may cause an interrupt in PoE-PSE support.

The debounce-interval of a gpio-keys node should be placed in the key
node itself, not in the main node. Move the properties added earlier and
fix the key node name while we're here.

When the reset button is next to the SFP cages, I2C operations on the
modules might cause interference on the button's GPIO line. Add a
debounce-interval of 5 times the poll-interval to ensure the line is
actually stable for some time and not just glitching.

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.

There is no need to keep a version specific dts directory.

This patch adds "dts-5.10" directory to use backported drivers.
There are several specification changes in the new drivers, so there
are some compatibility issues in using dts/dtsi files for 5.4.
The old DTS files are moved to "dts-5.4", so their corresponding
kernel version is obvious as well.

U-Boot uses the "bootpartition" variable stored in
"u-boot-env2" to select the active system partition. Allow
updates to enable system switching from OpenWrt.

The stock firmware of the ZyXEL GS1900 series use a non-standard
u-image magic. This is not enforced by the stock u-boot, which is
why we could boot images with the default magic. The flash
management application of the stock firmware will however verify
the magic, and refuse any image with another value.
Convert to vendor-specific value to get flash management support
in stock firmware, including the ability to upgrade to OpenWrt
directly from stock web UI.

The ZyXEL GS1900-8HP v1, v2 and GS1900-10HP are all built on a similar
Realtek RTL8380M platform. Create a common DTSI in preparation for
GS1900-8HP support, and switch to the macros defined in rtl838x.dtsi.
