realtek: copy dts directory for Kernel 5.10

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]
