drivers: net: fsl-mc: fix MAC address fixup procedure

In the process of adopting CONFIG_DM_ETH on the DPAA2 based platforms,
interfaces which were previously defined as "xgmii" were transitioned to
be defined as "xfi" in the DTS.
See the commit below for reference:
commit 87274918f2f4 ("arm: dts: ls2088ardb: add DPMAC and PHY nodes")

Then Vladimir's commit replaced all occurrences of "xfi" with
"10gbase-r" in an effort to make U-Boot work with the same device tree
as Linux.
commit 77b11f760416 ("net: replace the "xfi" phy-mode with "10gbase-r"")

These changes to the phy_interface_t of an Ethernet port meant that the
mc_fixup_mac_addrs() function was no longer capable to properly fixup
the MAC addresses. The problem arises from the fact that the hardcoded
information about an interface (wriop_get_enet_if()) was no longer
matching any actual device.

For example, the function tried to search for "DPMAC1@xgmii1" by name
using eth_get_dev_by_name() when only "DPMAC1@10gbase-r" was available.

This function removes the need to rely on the hardcoded information by
iterating through all the UCLASS_ETH devices which are DPAA2 and request
a fixup for each of them.
