e1000e: change k1 configuration on MTP and later platforms
Starting from Meteor Lake, the Kumeran interface between the integrated
MAC and the I219 PHY works at a different frequency. This causes sporadic
MDI errors when accessing the PHY, and in rare circumstances could lead
to packet corruption.
To overcome this, introduce minor changes to the Kumeran idle
state (K1) parameters during device initialization. Hardware reset
reverts this configuration, therefore it needs to be applied in a few
places.
