Driver missed initializing num_por which is por values that driver
configures to hardware. In order to get this values, add a new structure
ethqos_emac_driver_data which holds por and num_por values and populate
that in driver probe.

Fixes: a7c30e62d4b8 ("net: stmmac: Add driver for Qualcomm ethqos")
