RISC-V Devicetrees for v6.5 Part 2

T-Head:
 Add a basic dtsi, Kconfig bits & trivial binding additions for the T-Head
 1520 SoC (codename "light"). This SoC can be found on the Lichee Pi 4a,
 for which a minimal dts is added.
 
 Misc:
 Re-sort the dts Makefile to be in alphanumerical order by directory.
