net: freescale: ucc_geth: Return early when TBI PHY can't be found

Browse source

In ucc_geth's .mac_config(), we configure the TBI Serdes block represented by a
struct phy_device that we get from firmware.

While porting to phylink, a check was missed to make sure we don't try
to access the TBI PHY if we can't get it. Let's add it and return early
in case of error
