arm64: dts: ti: k3-j784s4-j742s2-main-common: Fix serdes_ln_ctrl reg-masks

commit 38e7f9092efbbf2a4a67e4410b55b797f8d1e184 upstream.

Commit under Fixes added the 'idle-states' property for SERDES4 lane muxes
without defining the corresponding register offsets and masks for it in the
'mux-reg-masks' property within the 'serdes_ln_ctrl' node.

Fix this.
