ARM: dts: rockchip: remove #address-cells and #size-cells from i2s nodes

An experimental test with the command below gives
for example this error:

arch/arm/boot/dts/rk3036-evb.dt.yaml: i2s@10220000:
'#address-cells', '#size-cells'
do not match any of the regexes: 'pinctrl-[0-9]+'

'#address-cells' and '#size-cells' are not a valid property
for i2s nodes, so remove them.
