Subject: [PATCH] arm64: dts: ti: k3-am69-sk: Add idle-states for remaining SERDES instances

In AM69 SoC there are 4 instances of the 4 lane SERDES. So in
"serdes_ln_ctrl" node there are total 16 entries in "mux-reg-mask"
property. But "idle-states" is defined only for the lanes of first two
SERDES instances. For completeness, set the "idle-states" of lanes of
remaining SERDES instances to a default value of "unused".
