arm: dts: k3-am654-base-board: Fix cpsw_nuss power-domains property

The commit 355be915ed08 ("arm: dts: k3-am654: Update power-domains
property for each node") has updated the power-domain cells value
and updated power-domains property in various existing dts nodes but
missed updating the cpsw_nuss node. This results in the following
build warning, fix this.

arch/arm/dts/k3-am654-base-board.dtb: Warning (power_domains_property): /interconnect@100000/interconnect@28380000/cpsw_nuss@046000000:power-domains: property size (8) too small for cell size 2
