cxgb4 : retrieve port information from firmware
issue get port information command to firmware to retrieve port information and update if it is different from what was last recorded and also add indication for supported link modes for firmware port types FW_PORT_TYPE_SFP28, FW_PORT_TYPE_KR_SFP28, FW_PORT_TYPE_CR4_QSFP.
