net: phy: nxp-c45-tja11xx: add TJA112X PHY configuration errata



commit a07364b3 upstream.

The most recent sillicon versions of TJA1120 and TJA1121 can achieve
full silicon performance by putting the PHY in managed mode.

It is necessary to apply these PHY writes before link gets established.
Application of this fix is required after restart of device and wakeup
from sleep.
