arm: dts: k3-am642: main_i2c0 cleanup 

move main_i2c0, main-i2c0-pins-default, and tca9554
definitions to where they belong i.e. k3-am642-evm.dts

k3-am642-r5-evm.dts is not cleaned up like in upstream
to include k3-am642-evm.dts so we have to add the
main-i2c0-pins-default and tca9554 nodes to it
as well.
