Commit 147271209a9d ("net: asix: fix operation without eeprom") added a special handling for ASIX 88772B that enable another type of header. This break the driver in DM mode as the extra handling needed in the receive path is missing.

However this new header mode is not required and only seems to increase the code complexity, so this patch revert this part of commit 147271209a9d.

This also reverts commit 41d1258aceb45b45f9e68f67a9c40f0afbc09dc9 ("net: asix: Fix AX88772B when used with DriverModel") of late.
