The T2080RDB boards revision D and up have updated Aquantia PHYs on the
two 10Gbps copper ports connected to MAC1 and MAC2 (from AQ1202 to
AQR113C). The second PHY connected to MAC2 is located at a different
address on the MDIO bus compared to revision C boards. Device tree
fixups are required for both Linux and u-boot to set the correct PHY
address for the new board revisions.

The first patch in the series implements a callback that detects the
board revision based on the CPLD registers.

The second patch updates the PHY addresses in u-boot for the legacy,
non-DM, driver implementation.

The third patch adds a fixup for Linux's device tree that is called from
both DM and non-DM code paths.

The last patch corrects u-boot's device tree under DM based on a newly
introduced CONFIG_T2080RDB_REV_D build option. We are unable to use the
board_fix_fdt callback to update the device tree before relocation because
the dts is stored in flash at that point and isn't writable. Instead,
the config option is used until a more robust solution is implemented.
Defconfig targets with the config option enabled by default are added for
