arm: dts: ls2088ardb: add DPMAC and PHY nodes

In order to maintain compatibility with the Linux DTS, the entire fsl-mc
node is added but instead of being probed by a dedicated bus driver it
will be a simple-mfd.

Also, annotate the external MDIO nodes and describe the PHYs (4 x AQR405
and 4 x CS4340). Also, add phy-handles for the dpmacs to their
associated PHY.
