-bgmac: add supprot for BCM4707

+Subject: [PATCH 4/5] bgmac: reset all cores on Northstar SoC
+
+On the Northstar SoC (BCM4707 and BCM53018) we have to enable all GMAC
+cores when we just want to use on. We iterate over all the cores and
+activate them.
+
+Subject: [PATCH 5/5] bgmac: add support for Northstar SoC (BCM4707, BCM53018)
+
+This adds support for the Northstar SoC. This SoC does not have a PMU in
+bcma and no register on it should be called. In addition it support 2.5
+GBit/s Ethernet to the PHY.
+
+This GMAC core is not fully working there are still problems with the
+DMA controller.
