Port_sts is a thing of the past for this driver. It was something present on the initial implementation of this driver and parts of the original struct were dropped over time. Using an array of int to store if a port is enabled or not to handle PM operation seems overkill. Switch and use a simple u8 to store the port status where each bit correspond to a port. (bit is set port is enabled, bit is not set, port is disabled) Also add some comments to better describe why we need to track port status.
