[PATCH] net: phy: resume phydev when PHY_RESUMING

[Zhangfei Gao <zhangfei.gao@linaro.org>]

Commit be9dad1f9f26604fb suspend phydev when going to HALTED.
However not to resume phydev when going to RESUMING.
BMCR_PDOWN remains set "ifconfig eth0 down" -> "ifconfig eth0 up".
Unless phy_attach_direct is called in open function.

Fix the issue via phy_resume in PHY_RESUMING
