I had also some problems when I switched to DM (but for other NXP
IMX6Q based board - mccmon6). It turned out that the time between probe
in the driver and first read of MDIO was just as in spec (or too short).
As a result the PHY was sometimes in uninitialized state, and silently
read 0x as ID, which prevent us from normal work.
The fix in this case was to increase the delay between powering up PHY
and exiting the ETH driver probe:

Please check if this patch (from this series):
"pcm052: bk4: Add board_phy_config() for BK4 to setup ksz8081 phy"
is not solving your problem.

For some reason while the FEC prior to DM was rock solid on Vybrid with
DM it at times only sends stuff but refuses to receive packets. Do you
recall having any such issues? Could it have to do with us using FEC1
by default rather than FEC0? But then at times it works just fine again
which is rather strange...
