Subject: [PATCH net-next v2 05/11] net: stmmac: platform: provide stmmac_pltfr_probe()

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

Implement stmmac_pltfr_probe() which is the logical API counterpart
for stmmac_pltfr_remove(). It calls the platform's init() callback and
then probes the stmmac device.
