arm64: dts: ti: k3-j784s4-j742s2-main-common: Fix length of serdes_ln_ctrl

commit 3b62bd1 upstream.

Commit under Fixes corrected the "mux-reg-masks" property but did not
update the "length" field of the "reg" property to account for the
newly added register offsets which extend the region. Fix this.
