Subject: net: phy: Allow EEE for all RGMII variants

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit 7e14069651591c81046ffaec13c3dac8cb70f5fb ]

RGMII interfaces come in multiple flavors: RGMII with transmit or
receive internal delay, no delays at all, or delays in both direction.

This change extends the initial check for PHY_INTERFACE_MODE_RGMII to
cover all of these variants since EEE should be allowed for any of these
modes, since it is a property of the RGMII, hence Gigabit PHY capability
more than the RGMII electrical interface and its delays.
