The Broadcom bcm54810 and bcm54811 PHYs are capable to operate in
simplified MII mode, without TXER, RXER, CRS and COL signals as defined
for the MII. While the PHY can be strapped for MII mode, the selection
between MII and MII-Lite must be done by software.

Please could you say more about what mii-lite is. Rather than adding a
bool DT property, i'm asking myself should we add interface mode for
it?

Is it a mode of its own? MII normally means Fast Ethernet, 100Mbps. Is
that what MII-Lite supports? How does it differ from RMII? Should we
be calling this PHY_INTERFACE_MODE_LMII?
