[PATCH net-next] net: mscc: ocelot: Fix probe for vsc7514

[Horatiu Vultur <horatiu.vultur@microchip.com>]

The check for parsing the 'phy-handle' was removed in the blamed commit.
Therefor it would try to create phylinks for each port and connect to
the phys. But on ocelot_pcb123 and ocelot_pcb120 not all the ports have
a phy, so this will failed. So the probe of the network driver will
fail.

The fix consists in adding back the check for 'phy-handle' for vsc7514
