[PATCH net-next v2] net: mdiobus: Debug print fwnode handle instead of raw pointer

[Alexander Dahl]

Was slightly misleading before, because printed is pointer to fwnode,
not to phy device, as placement in message suggested.  Include header
for dev_dbg() declaration while at it.

Output before:

    [  +0.001247] mdio_bus f802c000.ethernet-ffffffff: registered phy 2612f00a fwnode at address 3

Output after:

    [  +0.001229] mdio_bus f802c000.ethernet-ffffffff: registered phy fwnode /ahb/apb/ethernet@f802c000/ethernet-phy@3 at address 3
