Enric Balletbo i Serra ccf899a27c smsc911x: power-up phydev before doing a software reset. 
With commit be9dad1f9f ("net: phy: suspend phydev when going
to HALTED"), the PHY device will be put in a low-power mode using
BMCR_PDOWN if the the interface is set down. The smsc911x driver does
a software_reset opening the device driver (ndo_open). In such case,
the PHY must be powered-up before access to any register and before
calling the software_reset function. Otherwise, as the PHY is powered
down the software reset fails and the interface can not be enabled
again.

This patch fixes this scenario that is easy to reproduce setting down
the network interface and setting up again.
