Change the compatible string to "fsl,etsec2" for the Ethernet ports,
which is used in the current driver's match table.

The current code accesses eTSEC registers using physical
address directly, it's not correct, though no problem on
current platforms. It won't work on platforms, which does
not support 1:1 virtual-physical address map.

When an eTSEC is configured to use TBI, configuration of the
TBI is done through the MIIM registers for that eTSEC.
For example, if a TBI interface is required on eTSEC2, then
the MIIM registers starting at offset 0x2_5520 are used to
configure it.

Although I am unclear how the G&D MPC8308 boards
(arch/powerpc/dts/gdsys/mpc8308.dtsi) have ever probed their TSEC
interfaces. Probably not based on DM, since the fsl,tsec compatible
string has never been supported by the mainline tsec driver.

Missing a check

    if (reg == FDT_ADDR_T_NONE)
        return -ENOENT;

I agree with you, they seems using legacy driver. I'm working on the support
of compatible "gianfar", the MPC8308 boards can shift to the DM driver then.
