Subject: xgene: Always get clk source, but ignore if it's missing for SGMII
 ports
Patch-mainline: v4.13-rc5
Git-commit: aaf83aecd294fd61db6b34051f718f3e7ea34c22
References: bsc#1048501

Even the driver doesn't do anything with the clk source for SGMII
ports it needs to be enabled by doing a devm_clk_get(), if there is
a clk source in DT.

Fixes: 0db01097cabd ('xgene: Don't fail probe, if there is no clk resource for SGMII interfaces')
