rtl83xx.dtsi was once (presumably) created as a base for both RTL838x
and RTL839x SoCs. Both SoCs have a different CPU and the peripherals
require different compatibles. Fold rtl83xx.dtsi into rtl838x.dtsi,
currently only supporting RTL838x SoCs, and create the RTL839x base
include later when required.
