arm64: dts: rockchip: Add port subnodes to RK356x SATA controllers

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.
