The CPU peripherals on RTL83xx/RTL930x are connected to the CPU via the
Lexra bus. This bus can provide a clock signal to these peripherals, but
no clock driver is currently available. Instead, use a fixed-clock to
provide the clock frequency, and update the dependent peripherals.
Lexra bus clock frequencies:
- RTL838x: 200MHz
- RTL839x: 200MHz
- RTL930x: 175MHz

All current devices use identical bootargs, so let's move that to the
common devicetree includes.

On the devices with PoE support, the secondary UART (uart1) on the SoC
is used to communicate between the SoC and controller.
Enable the secondary UART on the following devices:
- D-Link DGS-1210-10P
- Netgear GS110TPP v1
- Netgear GS310TP v1
- ZyXEL GS1900-8HP v1/v2
- ZyXEL GS1900-10HP
- ZyXEL GS1900-24HP v2

The new backported GPIO driver supports interrupt, so use gpio-keys
instead of gpio-keys-polled for keys connected to the internal GPIO
controller.

this patch includes the following changes:
- adjust mapping for the new driver
- GPIO 24 -> GPIO 0
- GPIO 47 -> GPIO 0 (+ disabling system LED)
- disable pins in the invalid range
(out of the range 0-31 of the new driver)
- are these pins on the external RTL8231 (&gpio1)?
- GPIO 67 (-> GPIO 3 on &gpio1?)
- GPIO 94 (-> GPIO 30 on &gpio1?)
- drop "indirect-access-bus-id" property from gpio0 node in device dts
files

This patch adds a pinctrl-single pinmux node to allow disabling system
LED and enabling GPIO 0 (old driver: GPIO 24).

this patch updates SoC dtsi (rtl838x.dtsi, rtl930x.dtsi) for the
following backported drivers:
- gpio-realtek-otto (5.13)
- spi-realtek-rtl (5.12)
- irq-realtek-rtl (5.12)
And, disable SoC GPIO node (gpio0) in rtl930x.dtsi in dts-5.10.
Currently, the upstreamed driver doesn't support the GPIO controller on
RTL930x SoC.

the following changes are included in this patch:
- node is enabled by default, drop 'status = "okay"'
- adjust order of "compatible" lines and "reg" lines
- add a new blank line before fixed-link node in rtl830x.dtsi

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.
