ar8216: display flow control info in swconfig get_link in case of autonegatiation too

Browse source 
The swconfig get_link attribute (at least) on AR8327/AR8337 doesn't
consider the autonegotiated flow control.
AR8327/AR8337 provide the info about autonegotiated rx/tx flow control
in bits 10 and 11 of the port status register.
Use these values to display info about autonegotiated rx/tx flow
control as part of the get_link attribute.

Successfully tested on TL-WDR4900 (AR8327 rev.4) and
TL-WDR4300 (AR8327 rev.2).
