[PATCH RFC net-next 1/7] net: stmmac: remove unnecessary checks in ethtool eee ops

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Phylink will check whether the MAC supports the LPI methods in
struct phylink_mac_ops, and return -EOPNOTSUPP if the LPI capabilities
are not provided. stmmac doesn't provide LPI capabilities if
priv->dma_cap.eee is not set.

Therefore, checking the state of priv->dma_cap.eee in the ethtool ops
and returning -EOPNOTSUPP is redundant - let phylink handle this.
