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.

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.

[change "dts" to "dts-5.4", adjust Makefile]
