net: stmmac: fix num_por initialization

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

Fixes: a7c30e62d4 ("net: stmmac: Add driver for Qualcomm ethqos")
