Subject: [PATCH v2 5/9] net: stmmac: make stmmac_mdio_reset non-static

From: Srinivas Kandagatla <srinivas.kandagatla@...com>

This patch promotes stmmac_mdio_reset function from static to
non-static, so that power management functions can decide to reset if
the IP comes out from lowe power state specially hibernation cases.
