Subject: [PATCH 3/9] net: stmmac: qcom-ethqos: use generic device
 properties

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

In order to drop the dependency on CONFIG_OF, convert all device property
getters from OF-specific to generic device properties and stop pulling
in any linux/of.h symbols.
