Merge branch 'Convert-Broadcom-B53-to-mac_link_up-resolved-state'

Russell King says:

====================
Convert Broadcom B53 to mac_link_up() resolved state

These two patches update the Broadcom B53 DSA support to use the newly
provided resolved link state via mac_link_up() rather than using the
state in mac_config().
====================
