66140820e1 realtek: ZyXEL GS1900-48: drop status from gpio1
The default value for a DT node's status property is already "okay", so
there's no need to specify it again. Drop the status property to clean
up the DTS.

1ca081000a realtek: consolidate bootargs again
Bootargs for devices in the realtek target were previously consolidated
in commit af2cfbda2b ("realtek: Consolidate bootargs"), since all
devices currently use the same arguments.

Commit a75b9e3ecb ("realtek: Adding RTL930X sub-target") reverted this
without any argumentation, so let's undo that.

Commit 0b8dfe0851 ("realtek: Add RTL931X sub-target") introduced the
old bootargs also for RTL931x, without providing any actual device
support. Until that is done, let's assume vendors will have done what
they did before, and use a baud rate of 115200.

Fixes: a75b9e3ecb ("realtek: Adding RTL930X sub-target")

47f5a0a3ee realtek: Add support for ZyXEL GS1900-48 Switch
The GS1900-48 is a 48 + 2 port Gigabit L2 switch with 48 gigabit ports.
Hardware:
    RTL8393M SoC
    Macronix MX25l12805D (16MB flash)
    128MB RAM
    6 * RTL8218B external PHY
    2 * RTL8231 GPIO extenders to control the port LEDs, system LED and
    Reset button

2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules.

Power is supplied via a 230 volt mains connector.
The board has a hard reset switch SW1, which is is not reachable from the outside.
J4 provides a 12V RS232 serial connector which is connected through U8 to
the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC.
To connect to the UART, wires can be soldered to R603 (TX)  and R602 (RX).

Installation:
Install the squashfs image via Realtek's original Web-Interface.
