bcm53xx: update the ethernet core hacks
The PHY always says there is no link Instead of doing this dma sync a mdelay does the same trick and it is as unreliable. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@39202 3c298f89-4303-0410-b956-a3cf2f4a3e73

-bgmac: make bgmac work on systems without nvram
+These are some hackish patches to make the Ethernet driver work somehow
+on this arm core.
+The flash driver is not working, so we removed the nvram reading, this
+should be changed after we have a flash driver.
+The mdelay(1) is a ugly workaround for this arm chip, this seams to be a dma problem.
