Merge branch 'bcm63xx_enet-remove-mac_id-usage' 

Jonas Gorski says:

====================
bcm63xx_enet: remove mac_id usage

This patchset aims at reducing the platform device id number usage with
the target of making it eventually possible to probe the driver through OF.

Runtested on BCM6358.

Since the patches touch mostly net/, they should go through net-next.
