arm64: dts: rockchip: Align wifi node name with bindings in CB2

Since commit 3c36067 ("dt-bindings: wireless: bcm4329-fmac: Use
wireless-controller.yaml schema"), bindings expect 'wifi' as node name:

  rk3566-bigtreetech-cb2-manta.dtb: sdio-wifi@1: $nodename:0: 'sdio-wifi@1' does not match '^wifi(@.*)?$'
