dt-bindings: net: add fsl,erratum-a011043
Add an entry for erratum A011043: the MDIO_CFG[MDIO_RD_ER]
bit may be falsely set when reading internal PCS registers.
MDIO reads to internal PCS registers may result in having
the MDIO_CFG[MDIO_RD_ER] bit set, even when there is no
error and read data (MDIO_DATA[MDIO_DATA]) is correct.
Software may get false read error when reading internal
PCS registers through MDIO. As a workaround, all internal
MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
