net: dwc_eth_qos: remove the field phyaddr of the struct eqos_priv

Since the commit commit 6a895d039ba7 ("net: Update eQos driver and FEC
driver to use eth phy interfaces") the field phyaddr of driver private data
struct eqos_priv is no more used in eqos_start() for the phy_connect()
parameter.

Now this variable is only initialized in eqos_probe_resources_stm32()
it can be removed.
