Merge branch 'xgene-check-all-RGMII-phy-mode-variants' 

Iyappan Subramanian says:

====================
Check all RGMII phy mode variants

This patch set,
     - adds phy_interface_mode_is_rgmii() helper function
     - addresses review comment from previous patch set, by calling
       phy_interface_mode_is_rgmii() to address all RGMII variants

v2: Address review comments from v1
     - adds phy_interface_mode_is_rgmii() helper function
     - addresses review comment from previous patch set, by calling
       phy_interface_mode_is_rgmii() to address all RGMII variants
v1:
     - Initial version
