Subject: [PATCH 3/3] arm64: dts: ti: k3-j7200-main: Fix node has a unit name, but no reg/ranges property

If a node has unit name, then the node must include the
reg/ranges property.

This rule is not followed in the serdes_ln_ctrl and usb_serdes_mux nodes.

Warning is fixed by adding the reg property in the serdes_ln_ctrl
and usb_serdes_mux nodes.

Fixes: 1509295295c03 ("arm64: dts: ti: k3-j7200-main: Add SERDES lane control mux")
Fixes: 9a09e6e9cfcf5 ("arm64: dts: ti: k3-j7200-main.dtsi: Add USB to SERDES lane MUX")
