====================
net: macb: add support for MII on RGMII interface

This series adds support for MII mode on RGMII interface (patches 3/4,
4/4). Along with this the series also contains minor cleanups (patches 1/3,
2/3) on macb.h.

Changes in v2:
- added patch 4/4 to enable MII on RGMII support for SAMA7G5 MAC IPs
