Subject: xgene: Check all RGMII phy mode variants
Patch-mainline: v4.13-rc1
Git-commit: 326dde3e3b2ed05e5882e4401368d0f5d8861da7
References: bsc#1033621
This patch addresses the review comment from the previous patch set,
by using phy_interface_mode_is_rgmii() helper function to address
all RGMII phy mode variants.
