net: phy: Allow EEE for all RGMII variants
[ 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.
