This patch sets the setup_EEE function pointer to NULL for the
interfaces which do not support EEE. Currently only the KR backplane
interface (0x15AB) supports EEE. Setting this pointer to NULL prevents
EEE registers from being incorrectly modified and gives base drivers a
flag to check for EEE support.
