board: freescale: t208xrdb: add Linux fdt fix-ups for rev D
The T2080RDB boards revisions D and up have updated 10G Aquantia PHYs
connected to MAC1 and MAC2. The second Aquantia PHY is located at a
different address on the MDIO bus compared to rev C (0x8 instead of 0x1).
Fix-up the Linux device tree to update the PHY address for the second
Aquantia PHY on boards revisions D and up. Also rename the PHY node to
reflect the changes.
