Merge branch 'Convert-Broadcom-SF2-to-mac_link_up-resolved-state'

Russell King says:

====================
Convert Broadcom SF2 to mac_link_up() resolved state

Convert Broadcom SF2 DSA support to use the newly provided resolved
link state via mac_link_up() rather than using the state in
mac_config().
====================
