PHY: Add the phy_device_release device method.
Lately I've got this nice badness on mdio bus removal:
Device 'e0103120:06' does not have a release() function, it is broken and must be fixed.

Though actually there is nothing broken, it just device
subsystem core expects another "pattern" of resource managment.
This patch implement phy device's release function, thus
we're getting rid of this badness.
Also small hidden bug fixed, hope none other introduced. ;-)
