net: phy: nxp-tja11xx: log critical health state
...
TJA1102 provides interrupt notification for the critical health states
like overtemperature and undervoltage.
The overtemperature bit is set if package temperature is beyond 155C°.
This functionality was tested by heating the package up to 200C°
The undervoltage bit is set if supply voltage drops beyond some critical
threshold. Currently not tested.
In a typical use case, both of this events should be logged and stored
(or send to some remote system) for further investigations.
