phy: Add helper function to check phy interface mode

Browse Source 
Added helper function that checks phy_mode is RGMII (all variants)
'bool phy_interface_mode_is_rgmii(phy_interface_t mode)'

Changed the following function, to use the above.
'bool phy_interface_is_rgmii(struct phy_device *phydev)'
