Vladimir Oltean 0b5f0f29b1 net: phy: nxp-c45-tja11xx: enable MDIO write access to the master/slave registers 
The SJA1110 switch integrates TJA1103 PHYs, but in SJA1110 switch rev B
silicon, there is a bug in that the registers for selecting the 100base-T1
autoneg master/slave roles are not writable.

To enable write access to the master/slave registers, these additional
PHY writes are necessary during initialization.

The issue has been corrected in later SJA1110 silicon versions and is
not present in the standalone PHY variants, but applying the workaround
unconditionally in the driver should not do any harm.
