The SATA controllers on RK356x are identical to the ones found on RK3588, but don't yet provide a port sub-node. Per the datasheet the RK356x also supports the fbscp capability and has the same queue maximums. So add port sub-nodes to both sata controllers on RK356x, and move the phy properties to it. Also add phandles to the ports, so that boards can add their target-supply when available.
