KD20 got an IC+ phy, without the driver the phy is not properly
initialized resulting in ethernet not working unless being already
initialized by the vendor loader.
upstream commit 368b4d2b49bbbf379d9334747fbbd2aaaafe4356
drivers: net: remove dead drivers
removed icplus.c due to the lack of in-tree users.
Partially revert that commit adding back the IC+ driver.
